Developing location indicators for Agricultural Service Center: a Delphi–TOPSIS–FAHP approach

Abstract

The main goal of this paper is to construct objectives and attributes of the service centers location problem. This problem is often found within production management as a location problem, when designing for example supply chains or manufacturing layouts. The main contribution of this paper is constructing related location indicators. Since there was no similar literature in this discipline, so a Delphi survey applied to quantify expert's attitudes about location problem of Agricultural Service Center (ASC) and construct location selection attributes and also ASC objectives. A TOPSIS survey is done to rank extracted attributes to import in fuzzy analytical hierarchy process (AHP) study. Then a fuzzy AHP technique is applied to compute the weight of these most important attributes using four objectives, which obtained by Delphi technique too. In the simplest form with this assumption that all objectives have the same priority, the results illustrated that the service, cost, speed, and ASC profit are first to last important objectives, respectively. At the end of this paper, the multi-choice goal programming method recommended to use when the priorities of objectives are not the same. Finally, the weight of ASC location attributes computed to consider in ASC location problem.

A Sustainable Distribution Design for Multi-Quality Multiple-Cold-Chain Products: An Integrated Inspection Strategies Approach

“…They examined the problem of logistics and distribution of fresh products. Zangeneh et al [21] used an analytical hierarchical process (AHP) for the identification of factors affecting the distribution of cold-chain products. The study suggested to include cost, speed, and service of delivery in the analysis of relevant problems.…”

A decision support system for road freight transportation route selection with new fuzzy numbers

“…Barzekar et al (2011) used this method to investigate the criteria and indicators for sustainable ecotourism. Zangeneh et al (2015) considered identifying the agricultural service center location and used the method to construct the location objectives and attributes. Hanna and Noble (2015) determined effective criteria for environmental management and protection based on the input of expert researchers from Canada and the European Union using this method.…”

Optimization of Location–Routing Problem for Cold Chain Logistics Considering Carbon Footprint

“…The location of perishable food distribution centers was studied by Zvi Drezner [ 11 ], who suggested that the location of the distribution center would affect the inventory costs and location costs, so the two costs were considered in the total cost calculation. Morteza Zangeneh [ 12 ] proposed that service, cost, and speed were important factors influencing the distribution of fresh agricultural products, then the indicators that affect the location of agricultural service centers were identified, and the weights of these factors were calculated by fuzzy analytic hierarchy process.…”
