Abstract

This paper proposes an approach to the design and development of an intelligent Decision Support System (DSS) that is intended to help the selection process of alternative machines for Flexible Manufacturing Systems (FMS). The process consists of a series of steps starting with an analysis of the information and culminating in a conclusion —a selection from several available alternatives and verification of the selected alternative to solve the problem. In real decision situations, more than one criterion is present, and the problem becomes multicriteria decision making. The approach presented combines the Analytic Hierarchy Process (AHP) technique for multicriteria decision making with the rule-based technique for creating Expert Systems (ES). Such an approach allows the past experience, expressed as heuristics in ES, to be used. Moreover, this approach determines the architecture of the computer-based environment necessary for the decision support software system to be created. It includes the AHP software package (Expert Choice), Dbase III + DBMS, Expert System shell (EXSYS) and Turbo Pascal compiler (for the external procedural programs). As a result, a prototype decision support system for a fixed domain, namely a CNC turning center that is required to process a family of rotational parts, is developed. It helps the user to find the most “satisfactory” machine on the basis of several objective as well as subjective attributes.

    Keeping this in mind, Thomas L. Saaty introduced a simple yet systematic Analytic Hierarchy Process (AHP) method. It is a useful, and practical method and has been used as a tool for weight estimation in deriving valid argumentative decisions for machine selection in flexible manufacturing system [25], resource allocation by prioritizing information [26], supplier selection [10,27], reverse logistics and product recovery [28], selection of innovative educational project [29] etc. AHP is fundamentally built on two basic concepts: 1) formulation of the problem in a hierarchical structure, and 2) use of pairwise comparison.

    In their study, there were four main criteria: machine procedures, lead time, labor cost, and operation shift; and three alternatives: conventional machines, NC machines, and flexible manufacturing cells. Tabucanon et al. [37] developed a decision support framework designed to aid decision-makers in selecting the most appropriate machines for flexible manufacturing systems (FMS). The framework consists of two main stages.

    If traditional and AM systems could operate together in this way it would also have a favourable environmental impact. A decision-making framework or model to assist in selecting the manufacturing method and machine to apply to a component, based on size, material, geometric features and production factors, would be highly beneficial for such integrated systems [8,108–110]. The benefit of AM operating with traditional manufacturing as well as an independent industry become clear from the current scale of the two industries.

    However, given the fact that resources for enterprises are finite investments need to support the overall business strategy [54,55]. To that end, based on our experience with a number of SMEs, we have developed a methodological tool that employs at its core two effective and widely used tools in manufacturing decision-making processes, which complement each other well (e.g. [56–63]). On the one hand, Multi-Criteria Decision Aid (MCDA) considers quantitative and qualitative criteria with the possibility to appoint different weighting factors according to importance of the selected criteria, while on the other hand, data envelopment analysis (DEA) offers crucial insights about the different alternatives’ efficiencies, thus creating benchmarks.

    The use of AHP in manufacturing systems is widespread. The technique is used to justify investment in flexible manufacturing systems (FMS) [9,58], for choosing machines for FMS [42,57], the best FMS design [10,50], the most appropriate computer-integrated manufacturing (CIM) alternatives [64], for facility layout design [26], for real-time scheduling and part routing in advanced manufacturing systems [8], etc. Much of the literature is dedicated to justifying the choice or introduction of advanced manufacturing technology (AMT).
