“…Many attempts have been carried out for solving the MHESP during the last 3 decades. In a general classification, these studies can be categorized into the following four classes: (1) decision support systems (expert system for the design of repetitive manual materials handling tasks [68], the material handling expert system [69], the prototype expert system for the selection of industrial truck type, an expert consultant for in-plant transportation equipment [70], and a knowledge-based system for the choice of conveyor equipment [71]); (2) hybrid methods (an intelligent knowledge-based expert system, named intelligent consultant system, for selection and evaluation of material handling equipment, which has been composed of the following four models: equipment and their attributes, a rule-based database for selecting type of equipment, an MCDM technique (AHP) for selection of optimal equipment, and simulators to evaluate the performance of the equipment model [72], a decision support system based on axiomatic design principles [73], and a hybrid fuzzy knowledge-based expert system and genetic algorithm for the selection and assignment of the most appropriate MHE [74]); (3) optimization formulations (an integer programming model for minimizing material handling costs in manufacturing systems or warehousing facilities [75], a hybrid methodology including the integer programming formulation for designing layout and material handling system simultaneously [76], a 0-1 integer programming model to determine operation allocation and selection of material handling system in an flexible manufacturing systems simultaneously [77], a mathematical model to implement problem modeled by radio-frequency identification technology [78], and a multi-objective optimization model for selection of material handling system for large ship [79]); (4) the MCDM problems (fuzzy axiomatic design principles for selecting automated guided vehicles [80], fuzzy AHP (FAHP), and decision-making trial and evaluation laboratory (DEMATEL)-ANP with geographic information system for the selection of the best space for leisure in a blighted urban site [81], FAHP and fuzzy additive ratio assessment for selection of conveyor [82], the fuzzy complex proportional assessment (COPRAS) method for evaluating performance measures of equipment in total productive maintenance [83], the AHP and TOPSIS methods for selecting the most appropriate tomography equipment [84], COPRAS, simple additive weighting, and TOPSIS for analyzing and prioritizing Rotor systems [85], FAHP, fuzzy entropy, fuzzy TOPSIS (FTOPSIS), and multi-objective mixed integer linear programming for the choice of MHE in warehouse [86], FAHP for bu...…”
