  • A Goal Programming Strategy for Bi-Level Decentralized Multi-Objective Linear Programming Problem with Neutrosophic Numbers   Order a copy of this article
    by INDRANI MAITI, Tarni Mandal, Surapati Pramanik 
    Abstract: This paper develops a goal programming (GP) algorithm to evaluate bi-level decentralized multi-objective linear programming problem (BLDMOLPP) in neutrosophic number (NN) environment. In a BLDMOLPP a single decision maker (DM) is present at the upper level and multiple decision makers at the lower level. Here the parameters of the problem are considered to be NNs in the form of [P+QI], where P and Q are real numbers and indeterminacy is represented through the symbol I. I is expressed in the form of a real interval as agreed upon by the DMs. The BLDMOLPP with NNs then gets converted into an interval BLDMOLPP. Using interval programming, the target intervals for the objective functions are identified and subsequently the goal achievement functions are constructed. The upper level DM provides some possible relaxation on the decision variables under his/her control to cooperate with the lower level DMs to attain a compromise optimal solution. Thereafter, goal programming (GP) models are formulated by minimizing the deviational variables and thereby obtaining the most satisfactory solution for all DMs. Finally, a numerical example demonstrates the feasibility and simplicity of the proposed strategy.

  • Measuring Dynamic Capabilities-Based Synergies Using Real Options in M&A Deals: Amazons Acquisition of Whole Food   Order a copy of this article
    by Andrejs ?irjevskis 
    Abstract: Dynamic capabilities have become well established as a new imperative for organizing M&A processes. However, understanding the full benefits and possible limits of real options applications to measure a dynamic capability-based (managerial) synergies remains a challenge. The author developed three propositions and justified them by application of dynamic capabilities framework and real options theory to highly strategic and not standard M&A deal: Amazons acquisition of Whole Foods in 2017. The illustrative case study made it possible to bridge together two streams of research on dynamic capabilities and real options. While the empirical application of the dynamic capabilities framework makes them more visible, the application of the real options is making dynamic capabilities measurable in the M&A deals. In the end, the author discusses theoretical and managerial contributions, limitations, and future work.

  • Use of known population median of study variable for elevated estimation of population mean   Order a copy of this article
    by S.K. Yadav, Dinesh Sharma, Hari Sharma 
    Abstract: In this research, we propound a new enhanced estimator of population mean of the variable under study utilizing the acquaintance on the known median of the main variable. We perusal the features of the sampling distribution of the suggested estimator up to the approximation of order one. The articulated estimator is collated with the competing estimators of the population mean, and the prerequisites of the proposed estimator to be more efficient over competing are derived. These conditions are put to the proof using the numerical example. The efficiencies are compared in terms of the mean squared errors.

  • Municipal Water Supplies Efficiencies in Gaza Strip: A Data Envelopment Analysis Approach   Order a copy of this article
    by Abdelrahman AbuSerriya, Hatem Abu Hamed, Salah Agha 
    Abstract: This paper reports the findings of a research carried out to evaluate the efficiency of municipal water supply systems using Data Envelopment Analysis (DEA). Input and output variables needed for DEA were identified using literature review and questionnaires. Input variables considered in this paper include Number of Connections (NC), Length of Water Network (LWN), Number of Employees (NE) and Maintenance and Operation Costs (MOC), while Total Revenues (TR) and Number of People Served (NPS) were used as output variables. Values of these variables were obtained for the existing 25 municipalities for the years of 2015, 2016, and 2017 and the averages of these variables were calculated and used in the model. The paper uses Charnes, Cooper and Rhodes model (CCR) and Banker, Chames and Cooper model (BCC). Results indicate that length of water network and maintenance and operation costs were the major sources of inefficiencies. It has been further found that the municipality size effect as represented by the number of connections; length of water network; number of employees or maintenance and operation cost on the efficiency is very small. Therefore, it was decided to use the CCR for the rest of the paper. In order to make results more tangible, benchmarks for each of the inefficient municipalities were identified such that each of the inefficient municipalities can learn from best practicing ones. It was found that only 5 efficient municipalities can be used as benchmarks for all the inefficient ones. Further, each of the non-efficient municipality is advised by how much to reduce some of its inputs in order to become efficient.

  • The Mediating Impact of Motive Fulfilment on the Relationship Between Supervisors and Volunteers Intention to Stay   Order a copy of this article
    by Queen Usadolo, Yvonne Brunetto, Silvia Nelson, Patrick Gillett 
    Abstract: In this study, the effects of relationships with immediate supervisors, or leader-membership exchange (LMX), on volunteers intentions to stay with their organisations through motive fulfilment are examined. Data were collected from 213 volunteers working in community nonprofit organisations in Queensland, Australia, and hypotheses tested with simple and multiple linear regression analysis. The findings show that the fulfilment of values, understanding, enhancement, social, and career motives partially mediated the effect of LMX on volunteers intentions to stay. The results indicate that motive fulfilment is important in promoting positive workplace outcomes by enhancing volunteer-supervisor relationships.

  • P-Model of Inventory Optimization for high technology multi-generation products under limited warehouse storage space   Order a copy of this article
    by Gaurav Nagpal, Udayan Chanda 
    Abstract: This research work puts forward the inventory optimization model for the high technology multi-generation products under the situation of limited warehouse storage space. It is assumed that the manufacturer has an own space which has a lesser opportunity cost of usage as compared to another rented space, that carries higher charges on per unit area basis. Therefore, the manufacturer utilizes the own storage space for the period of time where his own space is sufficient to keep the inventories. When its inhouse space is not sufficient to store all the inventories, it stores the excess inventories at the rented space. While the research work has been done on various demand patterns under such a scenario, there is no research present on the inventory optimization under storage space constraints for the generations of innovative products whose demand follow the Norton Bass Model of Innovation Diffusion. This paper lays down a model for inventory optimization, but also puts forward a few theorems on the dynamics of how the model behaves with the change in innovation effect, imitation effect, with the rent of the leased location and with the storage capacity of own location. Finally, the paper performs numerical illustrations to show the behavior of the proposed model.

  • Determinants of Tunisian multimodal travel choice: A hybrid model based on multinomial logit and wavelet transform   Order a copy of this article
    by Habiba Abdessalem, Aida Bouzir, Saloua 
    Abstract: This paper aims to analyzing Tunisian multimodal travel choice in the Sahel region using a hybrid model based on multinomial logit and wavelet thresholding. Data are collected through a questionnaire. Thereby, it is found that travelers choosing taxi-metro give a great importance to the trip comfort and the value of time but they do not react to a travel cost. However, the passengers choosing taxi-bus and taxi-hire are less interested in the travel comfort than the trip cost. The results underline also the positive impact of transfer facilities including restroom, seat, information, security agent and security tools on passengers comfort perception. For bus and hire transit, it is found that an adequate level of cleanliness, an easy access to hire station, the presence of restaurants and shelters and a minimum degree of crowdedness reduces significantly the burden of traveling and increases the using of taxi-bus and taxi-hire rather than taxi-metro.
    Keywords: multimodal choice; transit passengers; transfer facilities; multinomial logit model; wavelet thresholding; hybrid model.

  • DNA-SKA: A DNA Congruous Secure Symmetric Key Generation Algorithm   Order a copy of this article
    by Monika Poriye, Shuchita Upadhyaya 
    Abstract: An efficient algorithm DNA-SKA (DNA based Symmetric Key Algorithm) for generating secret keys for sensor nodes is proposed in this paper. The key feature of the proposed algorithm is the usage of a DNA sequence as an initial key which is proffered to be selected from National Council of Biotechnological Information (NCBI) database available publically. Authentication process is required to make a secure communication between nodes. The Base Station then provides both nodes with two unique DNA strands generated by the unwinding of a single DNA molecule selected from NCBI database. The nodes then perform a simple but ingenious mechanism on the strands to obtain a similar symmetric key to be used for further encryption of the data to be communicated between the nodes. Computationally, it is a light-weight algorithm and better suitable` for devices like sensor nodes because of their limited computing resources.

  • Binary and Multi-class Classification of Android Applications using Static Features   Order a copy of this article
    by Meghna Dhalaria, Ekta Gandotra 
    Abstract: In recent years, the Android platform has ruled the market of smart mobile phones. As a result, there is a massive increase in Android applications such as banking, education and gaming etc. With the increase in the number of mobile applications and the dependency of users on these, Android has become the prime target of the attackers. Thus, the growth of sophisticated and complex Android malware is increasing that poses various threats such as stealing information, system damage etc. Thus, there is a need to find new ways to detect Android malware. For this purpose, machine learning algorithms have been used to build classifiers. To train such classifiers, there is a need of set of features that could describe the behavior of applications. Thus, we have created two datasets (binary and multiclass datasets) and made these publically available on GitHub. In this paper, a framework has been proposed which is capable of performing binary and multi-classification of Android applications. Static features such as Intents, Permissions, API calls and Command Strings are extracted from the applications and six machine learning algorithms are used to classify these into malicious and benign. Further, the malicious Android applications are classified into their families using the same machine learning algorithms. It is concluded that the accuracy of classification of malicious applications into the families gives very less accuracy (86.70% achieved by Random Forest) as compared to the binary classification accuracy (96.50% achieved by Random Forest).

  • Intellectual Capital efficiencies and performance of SMEs in KSA   Order a copy of this article
    by Mohammad Naushad, Shaha Faisal 
    Abstract: The advent of innovations and knowledge-based businesses has expanded the importance of Intellectual Capital (IC) in their performance. IC is considered as an assortment of intangible assets. Small and medium enterprises (SMEs), usually characterized by fewer tangible and higher intangible assets, have vast untapped potential to gain a sustainable competitive advantage by utilizing IC. The present paper is an endeavor to understand the impact of IC on SMEs' performance listed in the parallel market of Saudi Arabia called NOMU. The study measured the IC efficiency among the SMEs in KSA for the period from 2016 to 2018. The study, which is grounded in strong theoretical roots with a validated methodology, also identified IC's impact on profitability and productivity for the said duration among the quoted sector. Value Added Intellectual Coefficient (VAIC) was utilized as a proxy measure for IC. Return on Assets (ROA) and Assets to Turnover Ratio (ATO) has been used as the proxy measure of profitability and productivity, respectively. The Ordinary Least Square (OLS) regression method has been deployed to draw the impact of VAIC and its components upon SMEs' profitability and productivity. The results were statistically significant, indicating that VAIC impacts profitability and productivity. However, the components of VAIC failed to draw a significant impact on productivity. The study findings would help SMEs owners take note of IC and its components in reaching higher profitability and productivity levels.
