Taking a coking plant site in Qingdao as a research object, a scientific method is used to research and screen the remediation technology applicable to the organic contaminated soil in the site, which provides a reference for the screening of similar contaminated sites and the engineering application. Based on the characteristics of contaminated sites and the characteristics of remediation technology, the analytic hierarchy process (AHP) was used to qualitatively analyze and quantitatively calculate the three types of contaminated site remediation programs. AHP can simplify complex problems into hierarchical models, effectively solve multi-objectivedecision-making problems, and scientifically screen out the most suitable remediation schemes for contaminated sites.

A broad class of statistical decisionproblems are solved by minimax procedures which are Bayes with respect to discrete least favorable prior distributions. A general algorithm for specifying such distributions is presented which exploits the statistical properties of minimax procedures. The algorithm is demonstrated by characterizing the procedure which simultaneously minimizes a Bayes risk and a maximum risk under different loss functions in a simple multi-objective decision problem.

This paper concerns a static multi-objective control problem of the distributed parameter system, in which regionally decentralized plural decision-makers carry out control actions based on their own goals. The problem is formulated as minimization of vector functional to generate noninferior controls. Optimality conditions are derived. Moreover, we study a multi-objective decision problem to choose a preference optimal solution from among a set of non-inferior controls. We consider the following two cases; a) there exists a central decision-maker in the upper level (a central decisionproblem), and b) no central decision-maker exists and a collective decision is made (a collective decisionproblem). Two-level computational procedures using a constrained simplex method and an interior penalty method are presented for both cases. Gradient method is used for optimizing a system governed by partial differential equations.
