Demand Assignment: A DEA and Goal Programming Approach
نویسنده
چکیده
Assignment problem has always been a popular problem for production and operations research. There have been developed many methods and heuristics for these kinds of problems. This research deals with the problem of an automotive company’s driver belt assembly supply from its by-industry suppliers. Firstly, the suppliers are evaluated by data envelopment analysis (DEA), which is a mathematical modelling approach finding the relative efficiencies of the decision making units (DMUs). Later on, the suppliers that are found inefficient are eliminated and only the efficient suppliers are included for the assignment problem. Preemptive goal programming (PGP) is applied for the assignment of demand in order to satisfy the goals and the demand of the company by taking into account the priorities given by the company. Key-Words: DEA, Preemptive Goal Programming, Demand Assignment

A New Goal programming approach for cross efficiency evaluation
Cross efficiency evaluation was developed as an extension of DEA. But the traditional DEA models usually have alternative optimal solutions and, as a result, cross efficiency scores may not be unique. It is recommended that without changing the DEA efficiency scores, the secondary goal should be introduced for optimization of the inputs/outputs weights. Several reports evaluated the perfo...
متن کاملModified Goal Programming Approach for Improving the Discrimination Power and Weights Dispersion
Data envelopment analysis (DEA) is a technique based on linear programming (LP) to measure the relative efficiency of homogeneous units by considering inputs and outputs. The lack of discrimination among efficient decision making units (DMUs) and unrealistic input-outputs weights have been known as the drawback of DEA. In this paper the new scheme based on a goal programming data envelopment an...
متن کاملAdaptive aggregate production planning with fuzzy goal programming approach
Aggregate production planning (APP) determines the optimal production plan for the medium term planning horizon. The purpose of the APP is effective utilization of existing capacities through facing the fluctuations in demand. Recently, fuzzy approaches have been applied for APP focusing on vague nature of cost parameters. Considering the importance of coping with customer demand in different p...
متن کاملA Goal Programming Method for Finding Common Weights in DEA with an Improved Discriminating Power for Efficiency
A characteristic of data envelopment analysis (DEA) is to allow individual decision making units (DMUs) to select the most advantageous weights in calculating their efficiency scores. This flexibility, on the other hand, deters the comparison among DMUs on a common base. For dealing with this difficulty and assessing all the DMUs on the same scale, this paper proposes using a multiple objective...
متن کاملMeasuring a Dynamic Efficiency Based on MONLP Model under DEA Control
Data envelopment analysis (DEA) is a common technique in measuring the relative efficiency of a set of decision making units (DMUs) with multiple inputs and multiple outputs. Standard DEA models are quite limited models, in the sense that they do not consider a DMU at different times. To resolve this problem, DEA models with dynamic structures have been proposed.In a recent pape...
