摘要:

AbstractIssues of the cognitive validity of prescriptive decision‐aiding methods are discussed in this paper. In view of the difficulty of external validation, the focus is on internal validation of the user interface. The following criteria are applied to a variety of decision aid designs: (1) psychologically valid measurement of features impacted by the decision; (2) psychologically valid elicitation of decision maker's preferences incorporated into a decision rule which processes those features; (3) possibility of checking for decision maker's consistency; (4) possibility of providing him/her with an explanation of the aids finding

摘要:

AbstractThe Zionts‐Wallenius algorithm for multiple‐objective linear programming terminates with an extreme point solution that is locally but not necessary globally optimal. To find the globally optimal solution, a search along the facets of the solution space polyhedron may be required. In this paper we report the results of an experiment to determine how close the local and global optima are. We discuss the concept of closeness and propose one measure. Computer simulation is used to determine, in general, the quality of the solution found by the Zionts‐Wallenius method for two types of non‐linear utility functions. The merits of a search procedure are discussed in the context of the

摘要:

AbstractThe aim of this paper is to show how correspondence analysis can be a useful aid in multiple‐criteria decision making, particularly in the case of categorical criteria values. Under different types of input information, the technique is used to perform some preliminary analyses with a bonus of providing a simultaneous graphical representation of the alternatives and criteria. This picture can provide a better understanding of the structure of the two sets of variables to the decision maker before a decision is mad

摘要:

AbstractThe strategic decision of selecting an optimal flexible manufacturing system (FMS) configuration is a complicated question which involves evaluating trade‐offs between a number of different, potentially conflicting criteria such as annual production volume, flexibility, production and investment costs and average throughput of the system. Recently, several structured multicriteria approaches have been proposed to aid management in the FMS selection process. While acknowledging the non‐linear nature of a number of the relationships in the model, notably between batch size and the number of batches produced of each part, these studies used linear simplifications to illustrate the decision dynamics of the problem. These linear models were shown to offer useful analytical tools in the FMS pre‐design process. Owing to the non‐linearities of the true relationships, however, the trade‐offs between the criteria could not fully be explored within the linear framework.This paper builds on the two‐phase decision support framework proposed by Stam and Kuula (1991) and uses a modified non‐linear multi‐criteria formulation to solve the problem. The software used in the illustration can easily be implemented, is user‐interactive and menu‐driven. The methodology is applied to real data from a Finnish metal product company and the results are compared with those obtained
