In this paper, we investigate an assignment problem in which cost coefficients are triangular intuitionistic fuzzy numbers. In conventional assignment problem, cost is always certain. This paper develops an approach to solve an intuitionistic fuzzy assignment problem where cost is not deterministic numbers but imprecise ones. Here, the elements of the costs (profits) matrix of the assignment pr...

In earlier work a toll pricing framework for congestion pricing has been developed for both fixed and elastic demand traffic assignment models as an alternative to traditional marginal social cost pricing. Within the framework it is possible to define alternative objectives such as minimizing toll costs, minimizing the number of toll booths, etc. This paper will report the results of recent com...

Modern engineering programs have to address rapidly changing technical content and have to enable students to develop transferable skills such as critical evaluation, communication skills and lifelong learning. This paper introduces a combined learning and assessment activity that provides students with opportunities to develop and practice their soft skills, but also extends their theoretical ...

This paper presents a search algorithm solving an elastic scheduling problem with alternative resources, where a feasible schedule with minimal costs on resources is demanded. The proposed technique is based on detecting ”problematic” precedence constraints defined between activities processed on different resources. Assignment of alternative resources is realized as an extension of the search ...

This paper discusses the first steps towards the definition of novel statistics and metrics that characterize networks in terms of the complexity they pose to the traffic assignment problem. Here, we follow an approach in which the assignment emerges from routes selected by learning agents. Specifically, we deal with issues related to how routes are coupled. We first define and quantify route c...

This paper investigates common (slack) due-date assignment single-machine scheduling with controllable processing times within a group technology environment. Under linear and convex resource allocation functions, the cost function minimizes (including weighted sum of earliness, tardiness, assignment, where weights are position-dependent) resource-allocation costs. Given some optimal properties...

We study a model of interdomain routing in which autonomous systems’ (ASes’) routing policies are based on subjective cost assessments of alternative routes. The routes are constrained by the requirement that all routes to a given destination must be confluent. We show that it is NP-hard to determine whether there is a set of stable routes. We also show that it is NP-hard to find a set of confl...

A decision support platform is developed to evaluate and screen options for producing chemicals from biomass feedstock. The platform is based on the modelling of the socalled compartmental processing blocks (CPBs) and their connections. It includes a simulation tool and a synthesis/optimisation tool, both based on a central database which holds process and economic information about individual ...

At the early stages of the cooperative information system development one of the major problems is to explore the space of alternative ways of assignment and delegations of goals among system actors. The exploration process should be guided by a number of criteria to determine whether the adopted alternative is good-enough. This paper frames the problem of designing actor dependency networks as...
