Most existing methods for scheduling projects are based on centralized or hierarchical decision making using global models. So far, these methods have not produced the desired results, especially in highly dynamic multi-projects environments. In this study, we investigate a new method based on multi-agent systems and a combinatorial auction mechanism to allocate resources for the projects tasks...

In this paper, we consider a decentralized approach to the multi-agent target allocation problem where agents are partitioned in two groups and every member of each group is a possible target for the members of the opposite group. Each agent has a limited communication range (radius) and individual preferences for the target allocation based on its individual local utility function. Furthermore...

An attribute grammar is pure (left-to-right) multi-pass if a bounded number of left-to-right passes over the derivation tree suffice to compute all its attributes. There is no requirement, as for the usual multi-pass attribute grammars, that all occurrences of the same attribute are computed in the same pass, R is shown that the problem of determining whether an arbitrary attribute grammar is p...

In this paper we represent an efficient query optimization technique for the multi-valued rough relational database which follows the indiscernibility relation in its domain. This notion is perceived by using an encoding function to convert a multi-valued attribute to a constant single valued attribute. A simple select-querying technique is provided for selecting the tuples of single-valued att...

A criticism of mechanism design theory is that the optimal mechanism designed for one environment can produce drastically different actions, outcomes, and payoffs in a second, even slightly different, environment. In this sense, the theoretically optimal mechanisms usually studied are not "robust." In order to study robust mechanisms while maintaining an optimal contracting approach, we study a...

in this paper, we present a genetic algorithm (ga) for optimization of a multi-mode resource constrained time cost trade off (mrctct) problem. the proposed ga, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. beyond earlier studies on time-cost trade-off problem, in mrctct problem, resource requirements of each execution mo...
