To develop fuzzy environment selecton model, we first identified various Influential factors of ERP system selection and the corresponding indicators, that are used to evaluate those firms under aforementioned expectations. Expectations from a ERP software selection scale include particularly low risk, high quality, flawless product, reliability, delivery on time. We selected four ERP system selection firms(such as CA-MANMAN/X, BAAN, SSA-BPCS and SAP R/3),to evaluate their selection indicators and their weights in total score, so we interviewed with ERP users, the firms’s and corporation’s senior management cadre. Define the criteria for ERP system selection If there are more ERP alternatives in the list than expected, a pre-selection process should be used to reduce the number of alternatives to an acceptable level (three or four) so that the selection process will A new methodology for ERP software selection 4.1. Step 6:rank preference order choose an alternative with maximum toĤ. Step 5:caluate similarities to ideal solution * Step 4:caluate the distance of each alternative from A and A using the following equations: I is associated with benefit criteria and I is associate with cost criteria.

Conditional entropy and attribute significance concepts in rough sets theory are utilized in AHP to improve the judgment consistency. In this paper the concept of attribute significance in rough sets theory is utilized to solve evaluation bias problem in AHP. But, AHP is strongly connected to human judgment and pairwise comparisons in AHP may cause evaluator’s assessment bias which situation makes the comparison judgment matrix inconsistent. The AHP method is based on three principles: structure of the hierarchy, the matrix of pairwise comparison ratios and the method for calculating weights. #Software selection decision matrix how to#Analytic hierarchy process improved by rough set theory (Rough-AHP) AHP, developed by Saatty (1980), addresses how to determine the relative importance of a set activities in different decision-making processes. In our study, These identified five important dimensions of performance are Risk, Quality, Effectiveness, Efficiency, and customers satisfaction degree.Ģ. The importance of the actual software selection Influential factors must not be underestimated. Therefore, one of the most critical issues in implementation of an ERP system is the selection of the appropriate software to be used. ERP vendors use different hardware platforms, databases, and operation systems, and some ERP software is only compatible with some companies’ databases and operation systems. Introduction Any ERP software in market cannot fully meet the needs and expectations of companies, because every company runs its business with different strategies and goals. ![]() Keywords: Enterprise Resource Planning Software Selection Rough Set TOPSIS 1. In this paper, an integrated approach of ERP software selection analytic hierarchy process improved by rough sets theory (Rough-AHP) and fuzzy TOPSIS method is proposed to obtain final ranking. On the other hand, selecting ERP software is a multiple-criteria decision-making (MCDM) problem, and in the literature, many methods have been introduced to evaluate this kind of problem, which has been widely used in MCDM selection problems. ![]() 139, Fenglin 2nd Road, Changsha, 410205, China Ībstract Improperly selected ERP software may have an impact on the time required, and the costs and market share of a company, selecting the best desirable ERP software has been the most critical problem for a long time.
