Abstract
This study reviews some of the existing work in fuzzy multi-criteria decision making. According to the literature review, there is no research found in sequence selection in a single machine shop. The aim of this study is to select the best sequence in a single machine shop by fuzzy AHP. In the present paper, after introducing the efficiency indices in operation sequencing selection and a brief description of the fuzzy analytic hierarchy process method the way of using it is mentioned. The sequence calculated by the NBR algorithm is selected as the best sequence. The sequences calculated by the NBR, minimizes the launching and setup costs of the equipment.
Highlights
Analytic hierarchy process (AHP)The operation scheduling and sequencing consists of twoSince the correct and in time decision can have a steps
The the weight of the criteria and alternatives is shortest order time minimizes the flow and completion determined (Shi et al, 2007). The advantages of this average time, difference of the jobs maximum tardiness method compared to the other ones include its simplicity and completion date indices. It means that by means of and comprehensibility, the judgments incompatibility the shortest order time, a sequence is found that calculation possibility and the hierarchy structure of the minimizes a series of equivalent indices and by the process and the possibility of considering the quantitative earliest delivery date method, we find another sequence and qualitative criteria
We want to select a sequence among the four sequences each calculated by an algorithm (Hodgson, next best route rule analysis (NBR), earliest delivery date rule analysis (EDD) & SPT) and each minimizes one index
Summary
Since the correct and in time decision can have a steps. First, the orders or jobs are assigned to the considerable effect in reaching the goals, it is essential to resources and in each work center, in order to reach have a powerful technique that assists people in this field. The the weight of the criteria and alternatives is shortest order time minimizes the flow and completion determined (Shi et al, 2007) The advantages of this average time, difference of the jobs maximum tardiness method compared to the other ones include its simplicity and completion date indices. It means that by means of and comprehensibility, the judgments incompatibility the shortest order time, a sequence is found that calculation possibility and the hierarchy structure of the minimizes a series of equivalent indices and by the process and the possibility of considering the quantitative earliest delivery date method, we find another sequence and qualitative criteria.
