Development of geometry spot weld distribution model to improve efficiency of automotive body shop
by Selvam Ganesan, Prince Arockia Doss S
Abstract: In conventional car body process planning, parts and spots of an assembly get evenly distributed in geometry fixtures (or) stations. The remaining spots, over and above the cycle time of the geometry stations are moved to re-spot stations. Global trend of geometry and re-spot fixture distribution indicates that percentages of Geometry fixtures are higher in manual body shops with less than 40% of automation. The percentage of geometry stations varies up to 14% in 100% automated body shops. This trend shows the inappropriate planning of geometry and re-spot stations for manual and automated lines. The main focus area in the conventional planning is to set geometry through balanced distribution of parts and spots. Productivity is often not considered as the top priority. A geometry spot distribution model has been developed to resolve this concern. The proposed model can be used to calculate the appropriate geometry and re-spot stations required for a lean body shop. Improvement in quality establishment and productivity of the body shop are discussed in this paper with case studies. The developed methodology for appropriate spot weld distribution among the welding stations for body shop is simple to use for the product and process designers during any new product development phase. This can also be used for optimization of any existing cells of body shops.

How to increase organizational learning and knowledge sharing through human resource management processes?
by Reza Salehzadeh, Morteza Seddighi, Ehsan Ebrahimi
Abstract: The purpose of this paper is to examine how human resource management (HRM) processes and knowledge sharing affect organisational learning within the context of steel industry. Drawing from the literature on HRM, this study hypothesises and tests the relationship between HRM processes, knowledge sharing and organisational learning. The authors used survey research to collect the data. The PLS path modelling approach was used to analyse the data and the conceptual model. The empirical results from the structural model suggest that three out of five HRM processes (i.e., training, job design and job quality) influenced knowledge sharing. Furthermore, knowledge sharing was a direct antecedent of organisational learning.

Enhancing the performance parameters of flexible manufacturing system using decision-making techniques
by Anupma Yadav, Suresh C. Jayswal
Abstract: Due to varying requirements of customers, it became difficult for manufacturing firms to sustain their position in the market. Because of this, firms are finding and implementing new technologies in existing system and flexible manufacturing system (FMS) is one of the solutions for this problem. FMS is an automatic manufacturing system, capable of producing a wide variety of products with good quality. However, the cost of implementing FMS is high. So, decisions related with various parameters in implementing and managing the system, is one of the crucial steps in FMS. In present work, emphasis is done on developing a methodology that can make an appropriate decision of selecting best experiment level, by using simple calculations that can save money and time. For doing so, a relative study of decision-making approaches that combines Shannon entropy and weighted aggregated sum product assessment (WASPAS) method is performed for solving the selection problem of operating conditions. Criteria's weight is calculated first by Shannon entropy method. Later, alternatives were ranked by using calculated weights in WASPAS method. Based on obtained ranking, management could take verdicts for refining the performance parameters of the system.

Using queuing models to set the right parking price
by Baruch Keren, Yossi Hadad
Abstract: This paper applies queuing models (M/G/N/N) to determine the right price for parking, given that the arrival rate and the staying time depend on the parking price. The models explore the payment per hour and the entrance fee models, with one or several customer types, and where each customer type faces different prices (price discrimination). The models are also applicable for cases where the objective function is to set the park occupancy rate at a desired level. The analysis of the numerical examples demonstrates the applicability of the models and provides some interesting insights about the setting of the correct parking price under the appropriate pricing scheme. The conclusion is that one of the most important tools for process management and benchmarking of a car park is the parking pricing.

Engaging leadership, engaging environment, engaging job, and engagement
by Hasan Hosseini, Maryam Firouznia, Sayyed Mohsen Allameh
Abstract: The arrival of new workforce generation would necessitate a leadership type transcending traditional boundaries. Organisations must strive to develop a supportive work climate which inspires, strengthens and connects employees to perform their tasks vigorously. This paper primarily seeks to investigate the relationship between engaging leadership and work engagement. With reference to empirical studies and existing research on leadership and work engagement, a positive association between engaging leadership and work engagement mediated by engaging job and engaging environment is confirmed. More importantly, this study deals with the paucity of the structured literature regarding work engagement determinants, and offers a holistic model providing a logical ground for identifying empirical indicators and hypotheses to verify the theory. Apart from extending engaging leadership dimensions, certain paradigms are proposed for jobs and work environment to facilitate work engagement.

Holistic Approach of Optimizing Cross-Docking In Supply Chain
by Jyoti Mishra
Abstract: An initiative took in 1930s by the US trucking industries, cross-docking. The aim behind the initiative was to have lower inventory levels and optimised lead times by having an unbroken flow of product/material from the supplier to the end-customer. In order to have the seamless flow one must ensure that the operations are synchronising. Hence the optimisation of the overall supply chain to be more efficient in terms of lead time and cost, requires an interconnected and explicable connection of all the factors that has to be taken into consideration. The study conducted takes a real time model as an example and illustrates how cross-docking can be managed more holistically to synchronise cross-docking operations at the distribution centre with its inbound and outbound network logistics.

Linking Social Disruption and Firm Performance
by Satyendra Kumar Sharma, Saurabh Chadha, Himanshu Seth
Abstract: Traditionally the companies were focused on cost reduction by compromising its payoffs to maximise the entire supply chain's profit and its sustainability. Nevertheless, a new concept of socially responsible supply chains can overcome the limitations of traditional model and enhance the company's performance in consideration to triple bottom line approach. Most of the studies done empirically investigates and provide a conceptualised framework on supply chain sustainability but a dearth of studies impacting the socially responsible supply chain effect on the performance of firm, financially as well as socially creates a need of more research in this area. This study focused on four different events of social issues that hampered the company's performance in terms of share prices, revenues, profits and overall image in the eyes of stakeholders. The study includes qualitative as well as quantitative analysis to know the impact of social issues on supply chains leading to disruptions.

A Vendor Recommendation Model using Neural Networks
by Satyendra Kumar Sharma, Sajeev Abraham George
Abstract: Suppliers today are considered as a logical extension to a firm that provide critical inputs to its processes. Supplier performance evaluation is vital for any firm to carry out supplier selection and to practice effective supply chain management. Further, the supplier performance measurement system should continuously evolve in a company as a process for improving the capabilities, execution effectiveness and efficiency. Though the supplier performance systems have been well investigated in the literature, only very few studies have proposed an order-based supplier selection approach that takes into account the changing priorities of the customer. The research tries to address this gap by attempting to establish a dynamic linkage between customer order priorities and supplier characteristics. A neural network model for the order driven vendor recommendation system that ranks the suppliers as per the requirements of the order has been proposed.
Keywords: Vendor Selection; Neural Network; Case Application.
Machinability model and multi-response optimization of process parameters through regression and utility concept
by Ashok Kumar Sahoo, Amlana Panda, Bijaya Bijeta Nayak, Ramanuj Kumar, Rabin Kumar Das, Ramesh Kumar Nayak
Abstract: Over the years, it is essential to produce appropriate dimensional with quality parts for the use in various automotive components. This paper presents modelling and multi-optimisation exploration on the hard part turning of EN 24 grade steel at 48 HRC with coated carbide multilayer inserts for three roughness factors (Ra, Rz, and Rt). Taguchi L16 orthogonal design with three input parameters and three quality characteristics output was applied to suitably model the process requirements. The second model provides a high coefficient of determination (R2 = 0.98 for Ra, 0.97 for Rz and 0.95 for Rt respectively) compared with the linear model that demonstrates high significance. The ideal parametric setting for different multiple quality features was found to be the depth of cut (0.4 mm), feed rate (0.04 mm/rev) and cutting speed (200 m/min) respectively. The multi-responses optimisation has been simultaneously performed using Taguchi method and the utility concept.

On the benchmarking of port performance. A cosine similarity approach
by Iñigo L. Ansorena
Abstract: The measurement of port performance is not a simple task since there are many variables involved in port operations. Some industry standards are based on key performance indicators, which are the basis to provide management information for planning and control. We propose the use of cosine similarity to gain a better understanding of performance indicators. The concept of cosine similarity is particularly interesting when searching for similarities in big datasets. The name derives from the term direction cosine, i.e., two vectors are maximally similar if they are parallel (maximum value of cosine), and maximally dissimilar if they are perpendicular (90

Towards a LSRO model of industrial performance improvement: A case study of LSRO model implementation in an industrial SME
by Badr Elwardi, Anwar MEDDAOUI, Ahmed MOUCHTACHI, Ahmed EN-NHAILI
Abstract: The globalisation recognised in this century engages the third world to a strange competitive economic environment, the Moroccan Government highlights some emergency decisions to support the small and medium enterprises (SME) like decrease taxes and facilitate enterprise creation cost and procedure however those actions remain insufficient toward the external promotion reflected on delay, quality and cost of products and services. Hence, emergence of lean manufacturing system (LMS) came to resolve this problem by improving productivity, management system. However, for many manufacturers, especially SME, these concepts stay very difficult to implement and maintain. In this perspective, this work aims to overcome the optimum steps to install the advanced LSRO model to improve both productivity and performance with low cost. These implementation steps of LSRO model has been proposed through a case study relating basic concepts of LMS and management by objectives (MBO). Nevertheless, few works related to this field make academic research and industry closer, our work falls within this context through the industrial productivity improvement. This paper proposes also some research perspectives aiming to complete this research axis by enhancing the presented model through other industrial experiments and studies.

Development of a composite dynamic capability index for benchmarking new product development performance: An empirical study among industries in electronics sector
by Pratap Kumar Surendran Nair, Radha Ramanan, Muhammad Shafi
Abstract: The study is an attempt to develop a unique composite dynamic capability index to assess the capability of the new product development (NPD) unit and benchmark its performance with respect to competition. Combining the concepts of dynamic capability, quality management capability and data envelopment analysis (DEA), a unique composite dynamic capability index is proposed. New product development (NPD) units in the electronics industry are specifically chosen for the study due to its environmental dynamism where dynamic capabilities play a significant role in maintaining competitiveness. The proposed index is validated through an empirical study among 50 NPD units in the electronics manufacturing sector. The index is able to explain 71.1% of the variance in competitive performance, 62.8% variance in customer satisfaction and 46.8% variance in development time three of the four NPD performance parameters chosen for analysis. The application of DEA suggests specific targets for improving the efficiency of the NPD process.

Strategic Supplier Management: from contractual models to engagement partnerships
by Leandro Pereira, Carlos Jeronimo, João Lourenço
Abstract: Nowadays, it is essential to establish a good relationship between a company and its suppliers because otherwise, this relationship cannot last long. In the understanding of recent literature and empirical studies, there is still a lack of collaboration among customers and suppliers. There is a vision for short-term profit in big companies and less attention to the quality of services provided to them. The main objective of this study is to find mechanisms that make companies in the same supply chain thrive together. To this end, 15 companies that provide services to big companies in Portugal were interviewed to assess the problems and needs that exist in relation to this type of customer. The interviewed companies provided valuable information for this study. This allowed the design of two models of good practice in order to support companies in their relations with business partners.

Programming tasks in business processes like a realistic hybrid flexible Flow shop using genetic algorithms
by Jaime A. Arango-Marin
Abstract: An adaptation of the job scheduling to the programming of business process tasks is made in a hybrid flexible flow shop environment. The problem is modelled considering realistic situations: sequence-dependent task change times, malleability of batch sizes, variable transfer batch, objective function of minimising average tardiness, unrelated parallel resources and more than two stages To solve the problem, are proposed standard and modified genetic algorithms The results of the experimentation allow us to appreciate that both genetic algorithms achieve average tardiness values between 20% and 60% better than the dispatch rules with best performance of the modified genetic algorithm. The conclusions are that it is possible to schedule business process tasks as an industrial plant, that it is necessary to take account of the real environment requirements and that the best solution is reached when a smart technique adapted to the features of the problem is used.

Developing a commercialisation model for innovative products and processes in a petroleum firm
by Soranart Ngamcachonkulkid, Parames Chutima, Somboon Chuaykoblap
Abstract: In Thailand, the petroleum industry is a major contributor to the economy as a supplier of crucial petroleum products. However, due to its geographical location, many multinational oil and gas companies have established their operations in the country. For Thai petroleum firms to remain competitive in the industry, effective commercialisation strategies of inventions to innovations can bring firms competitive advantages in terms of financial returns, business opportunities for partnerships, and advanced operations. Nonetheless, commercialisation of inventions is becoming increasingly difficult due to changes in the market. Firms operating without an explicitly established commercialisation process are at a disadvantage. The objective of this research is to develop a formal commercialisation model suitable for commercialising product and process inventions in Thailand's petroleum industry. The methodology used in this research consists of three stages as follows: 1) develop a preliminary commercialisation model; 2) refine the model; 3) apply the model to a Thai petroleum firm as a case study. As a result, two commercialisation models are developed, namely an industrial commercialisation model and a company commercialisation model.
Keywords: commercialisation model; innovative products; petroleum firm.
Replenishment policy for deteriorating items with trade credit and allowable shortages under inflationary environment
by S.R. Singh, Shilpy Tayal, Anjali Gaur
Abstract: In this paper we have developed an inventory model for deteriorating items in which demand of the product is a function of expiration date. In such cases the demand for the product generally decreases as the product is nearer to its expiration date. The different cases based on the allowed trade credit period have been discussed under inflationary environment. Shortages are allowed and partially backlogged. To exemplify this model numerical examples for all the cases and sensitivity analysis with respect to important parameters have been provided. The convexities graphs and the variation in total cost with the changes in parameters are represented with the help of the graph. The objective of this paper is to find out the optimal ordering quantity by which one can minimise the total associated cost of the system.

What can we learn from process maturity models? – A literature review of models addressing process maturity
by Gunnar Dahlin
Abstract: The article provides an updated extensive literature review on process maturity. On a general level process maturity could be defined as the degree to which a process is defined, managed, measured, and continuously improved, where the aim of working with maturity is twofold, either to measure the level of maturity in order to compare with other processes or to identify improvement areas. According to the findings of this study there are areas indicating needs of further research. Firstly, the fundamentals of process management seem to be missing when describing the work with process maturity, which could affect the quality of maturity models. A second area of further research is related to the absence of approaches and methods for improving process maturity, since improving maturity is often addressed as 'what' to do, not 'how' to do.

A study on the performance measures of the non-Markovian model of optional types of service with extended vacation, reneging process and service interruption followed by phases of repair
by S. Maragatha Sundari, N. Murugeswari, P. Manikandan
Abstract: In this study on a non-Markovian queuing framework, clients arriving in batches follow a Poisson distribution. All the arriving clients have the alternative of picking any of the N sorts of services rendered. Service time follows general distribution. In addition, the system breaks down at random. Hence the server gets into repair process of two phases based on the fault, in first phase general repair is carried out. Then in the second phase repair based on the category is followed. Likewise after the system ends up with service, the serverwill go for a necessary vacation. In addition, an optional extended vacation is followed. In this vacation time, maintenance work is carried out. An additional aspect of reneging happens during the time of break down and vacation due to impatience of the customers. By the use of birth and death queuing process the conditions overseeing the model is framed. The probability generating queue size and queuing execution measures of the model are derived. The legitimisation of the model is finished by methods for numerical illustration. The graphical portrayal gives a reasonable picture about the procedure. Also, it gives significant thoughts for decrease the system break down, reneging and for the advance of the system speedier.
Keywords: non-Markovian queue; optional types of service; service interference; optional extended vacation; maintenance work; revamp process of two stages.

by K. Sivakumar, R. Jeyapaul, K.E.K. Vimal
Abstract: The paper proposes a framework for evaluating the organisational competitiveness attained through sustainable manufacturing. An assessment model using analytical hierarchal process (AHP) has been adopted for the evaluation of organisational competitiveness. A conceptual model is developed to understand the interrelationship between seven sustainable manufacturing practices and five organisational competitiveness with 14 sustainable manufacturing outputs at the intermediate level. The attainment of six organisational competitiveness is evaluated by computing the global priority scores of practices and outputs of sustainable manufacturing. The linkage matrix developed between the practices and the output of sustainable manufacturing and the output and organisational competitiveness is the significant contribution of this work that can be used by practicing managers/researchers to understand the various interactions and hence, promote the research in the field of sustainable manufacturing.
