• Genetic Algorithm Based Solution of Multiobjective Stochastic Transportation Problem  
  by Jaydeepkumar Mulajibhai Sosa, Jayesh M. Dhodiya 
  Abstract: In transportation problem (TP) a decision-maker (DM) always wishes to optimize the given objectives by effectively transporting a given item from several sources to several destinations. The present paper explores the genetic algorithm (GA) based hybrid approach to solve Multiobjective Stochastic Transportation Problem. By using exponential membership function, different shape parameters (SP) and aspiration levels (AL), higher degree of satisfaction for each objective function are obtained which provides more flexibility to the decision-maker (DM) for a better decision. In this approach, a multiobjective optimization problem first converted into a single optimization problem then GA is applied with operator selection, crossover, mutation, etc. The logistic distribution is used here to convert the stochastic supply and demand into the real value. Here, we consider the objective functions which are non-commensurable and conflict with each other. To interpret, evaluate, and exhibit the usefulness of the proposed method, a numerical example is given.

• Port Resiliency and the Effects of Hurricanes on Port Operations  
  by Dylan Folkman, Amir Gharehgozli, Joan Mileski, Cassia Bomer Galvao 
  Abstract: This paper studies the negative effects of hurricanes on port operations. Hurricanes push a large amount of sediment into the port and connecting channels, thus decreasing the water depth. As a result, larger vessels need extra time to de-ballast the water from the ballast tanks in order to reduce their draft and enter the port. Arena software is used to simulate port operations before and after a hurricane. The simulation study addresses how de-ballasting can impact the port key performance indicators. The model before a hurricane allows ships to enter the port, unload and load containers, and leave the port, while the after-hurricane model forces the large vessels to first empty their ballast tanks before entering the port. The simulation models are used to study the case of hurricane Harvey at the Port Houston. The results show that hurricanes have detrimental impacts on the port.

• A Hybrid Approach for Performance Evaluation and Ranking of Divisional Structure Organizations  
  by Saeed Zarghami, Maghsuod Amiri 
  Abstract: The success and survival of any organization depends on its performance. Performance evaluation is important because it monitors the system's performance and measures any organization's success in achieving goals and outputs based on inputs and used strategies. Most performance evaluation systems do not pay attention to the structure of organizations. Mechanistic structures include machine bureaucracy, professional bureaucracy, and divisional structure, which can be stated to have a functional nature. The divisional structure is multi-functional and supports multiple missions or functions. In this multi-functional structure, the overall performance of any organization is based on the aggregation of the performance of each functional section of the organization. As multi-criteria decision-making methods are very diverse and each method can produce different results, this study is based on the characteristics of the organizational structure, the views of managers, and the type of data, using axiomatic design. By answering the question of what we want to achieve and how to achieve it, the evaluation and ranking method is selected and calculation has taken place. According to the axiomatic design, each function efficiency score of division is achieved by Data Envelopment Analysis (DEA) in stage one. The efficiency score of each function is considered as inputs the criteria values of Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) in the second stage. In practice, the agreement between the stakeholders based on their needs in selecting the evaluation and ranking method is very important, and the axiomatic design responds well to this issue. Moreover, the results show that paying attention to the type of organization structure and rules governing it is effective in the evaluation and ranking process.

• Analyzing Impact of Strategies Adopted by Decision Makers on Performance Parameters of Bi Criteria Transportation Problem  
  by Subhra Das 
  Abstract: The most common methodology adopted for evaluation of optimal transportation schedule is the conventional cost benefit analysis which provides decision makers with a monetary assessment of a transportation schedule. A mechanism is needed to capture the impact of strategy adopted by decision makers in case of bi criteria transportation problem on the performance parameters like cost and time. In this paper, an algorithm has been proposed to solve bi-criteria transportation problem with the objective of minimizing both cost and time which satisfies the constraints of demand and supply. The algorithm also enables one to obtain the optimal transportation schedule by incorporating the decision makers priority towards cost and time. Consequently, the algorithm provides a scope to evaluate the impact of strategy adopted by decision makers in obtaining the optimal solution on total cost & time of transportation. The algorithm is explained with the help of an elaborate illustration. The result obtained by the proposed algorithm is compared with that suggested by researchers in the past for validation. The impact of variation in decision makers strategy is assessed in terms of percentage change in total cost of transportation and maximum time taken for transportation following the optimal route.

• Buffer estimation in the critical chain method by considering internal and external risks  
  by Hamed Asgari 
  Abstract: The critical chain method as a novel concept in project management has attracted most researchers and project managers' attention in recent years. In this regard, the estimation of buffer size plays an essential role in successful implementation. It has proved that if buffers in the critical chain are estimated in large quantities, the critical chain concept loss its productivity. On the other hand, lower buffer estimations cannot protect the project against unwanted events. As a result, reliability was reduced drastically. On the other hand, in most of the existing methods, only the internal risks of the project are considered. So one of the most critical risk factors which are related to outside the project is ignored. In this research, the internal and external source of uncertainty is considered simultaneously during the buffer estimation process. In this research, in order to identify the external risks of the project, the failure mode and effect analysis technique has been used. With the help of project experts, the factors that may disrupt planning have been identified in this method. Finally, the most important external risk is identified, and the amount of risk priority number of this factor is included in the buffer size estimation calculations. Additionally, the lognormal distribution function is utilized for stimulating activities duration as internal risk resources. Considering internal and external risks in a project will bring the results closer to real-world results. Finally, a real case study is experimented with to illustrate the effectiveness of the proposed model. Numerical instances show that the suggested buffer estimation method can be better than the traditional cut and paste method in projects. The results of this research can be used by various organizations and individuals and, at the same time, will facilitate project management. Taking into account the internal and external risks of the project at the same time can also lead to more accurate decisions in the field of project management.

• THE DISSEMINATION OF OPERATIONAL CAPABILITIES IN MANUFACTURING NETWORKS: A CO-EVOLUTIONARY PERSPECTIVE  
  by Cristiane Biazzin, Ely Paiva, Kenyth Freitas 
  Abstract: Although scholars have agreed on the relevance of capabilities to operations strategy and the competitive advantage of firms, the process by which they are disseminated among networks remains mostly unexplored. Since operational capabilities are difficult to imitate or acquire, manufacturing networks represent a favorable environment for the exchange of experiences, knowledge and the speeding up of the process of capability development. Based on the co-evolutionary theoretical perspective, this research aims to understand how operational capabilities are disseminated between headquarters and the plants in manufacturing networks. The study used multiple case studies to explore four organizations in three different industries. The findings demonstrate a possible relationship between the manufacturing stages proposed by Wheelwright and Hayes (1985) and the Co-evolutionary Theory. The co-evolution of manufacturing units and the dissemination of capabilities is a gradual process, comprises cumulative motivational factors, and involves actors from different dimensions that absorb these capabilities at different speeds.

• Analysis and assessment of divergence of final offers in Negotiation using Gamma and Beta distribution  
  by Sarin Abraham, Punniyamoorthy Murugesan 
  Abstract: The Final Offer Arbitration procedure is used to settle dispute where the parties involved propose different offers and an arbitrator choose one sides offer closer to his view of the fair offer as the final settlement. The competing parties try to guess the arbitrators view of the final settlement and then attempt to propose the same offer as that of the arbitrator. But, this prediction cannot be done exactly and most of the time the players would only expect the arbitrators preference to follow some distribution. This uncertainty about the arbitrators choice leads to a divergence between the final positions arrived by the two players. In this paper, the divergence between the equilibrium strategies has been computed for two distributions, namely, the Gamma and Beta distribution which were hereto not considered by other researchers. The computed divergence for the Gamma and Beta distributions are compared with the known divergence of other distributions to check the applicability of these distributions in the Final Offer Arbitration game.

• An Empirical Study on Effects of Risk Equity on Intercity Road Network Accessibility  
  by Abbas Mahmoudabadi, Donya Nader 
  Abstract: Since hazardous materials (Hazmat) transportation is always contaminated by transport risk, local/national authorities are dealing with the distributing of Hazmat transport risk to avoid risk aggregation over the most operational links but it affects the network accessibility which is dealt with by transport operators. The aim of this study is to investigate the effects of employing risk equity techniques on network accessibility through developing a mathematical model in which the maximum transport risk associated with the network links is minimized. The proposed mathematical models run using experimental data that composes of specific nodes, edges as well as Hazmat Origin-Destination matrix in medium size of intercity road network in the Iranian northern province of Guilan. The analytical experiments revealed transport risk distribution techniques have significant negative effects on network accessibility resulted in reducing road accessibility. Therefore, in terms of application, the authorities and transport planning experts should consider the effects of employing Hazmat transport risk equity on network accessibility prior to designing Hazmat transport networks.

• An empirical study of the merit-order effects in the Texas energy market via quantile regression  
  by Mary Rudolph, Paul Damien, Jay Zarnikau 
  Abstract: The merit-order effect is the tendency for non-dispatchable renewable energy generation (wind and solar), or baseload generation (nuclear), to lower wholesale market prices by shifting supply curves. To better quantify real-time pricing, we examine how the merit-order effects varies with the level of wholesale electricity prices in all the eight zones that comprise the Electric Reliability Council of Texas (ERCOT). To accomplish this goal, we quantify the merit-order effects due to nuclear, wind and solar energy resources. Among other results, we find that when wind generation increases by 10% median prices ($/MWH) in the North region of ERCOT decline by 1.47%, 1.04% and 1.24% for hours 3am, 11am and 4pm, respectively. The corresponding decline in median prices in the West region are 1.86%, 1.34% and 1.73%. These impacts vary considerably within ERCOT; moreover, transmission bottlenecks could mitigate energy transfer across the eight zones. Policy implications from our analysis are discussed.

• A training methodology based on Virtual Reality to promote the learning-by-doing approach  
  by Fabio Grandi, Margherita Peruzzini, Sara Cavallaro, Marcello Pellicciari 
  Abstract: Virtual reality (VR) training allows companies to train their workforce thanks to virtually simulated environments, leveraging the skills of people before the system production, with the final aim to reduce the downtime of productive equipment and improve the global factory efficiency. However, the use of VR immersive training is still limited in industry due to the lack of structured methodologies to effectively implement these simulations. This paper deals with the application of VR technologies to create virtual training simulations addressing assembly or maintenance tasks. It suggests a methodology to create an interactive virtual space in which operators can perform predefined tasks in a realistic way, having dedicated instructions to support the learn-by-doing, based on Key Training Features (KTFs). This methodology was applied to an industrial case study concerning some specific tractor assembly phases. Results show that operators generally appreciate this new training process, enabling faster and more intuitive learning.

• Innovative Framework for Lean & Green Complex Manufacturing Systems Using Value Stream Mapping  
  by Shyamal Samant, Ravi Prakash 
  Abstract: Lean manufacturing helps companies to enhance their productivity, quality, and reduce wastage. Value stream mapping (VSM) is an important tool for reducing lean wastes in the value stream. It is a very useful tool, however, it suffers from several shortcomings. VSM is a pencil and paper tool that gives only a static snapshot of the production value stream. It cannot be easily applied for a complex value stream involving multi-level bill of materials (BOM), or for the complete product. Moreover, VSM fails to analyze environmental impact caused due to the value stream. In order to address these limitations, this paper proposes a framework which integrates VSM, life cycle assessment (LCA), lean and green box score, and discrete event simulation (DES). LCA has been used for environment impact assessment. The lean and green box score has been used to monitor the operational, financial, resource capacity, and environment performance of the value stream. Discrete event simulation (DES) has been used for resource optimization. DES also helps in dynamic visualization of the production system. The proposed framework will help the manufacturers to improve their lean performance, and sustainability performance. It will also help in lean implementation in a complex production system. This framework has been explained through a case study of the supply chain of a gearbox manufacturing firm.
