Constraint Programming (CP) is a promising technique for managing uncertainty in conceptual design. It provides efficient algorithms for reducing, as quickly as possible, the domains of the design and performance variables while complying to the engineering and performance constraints linking them. In addition, CP techniques are suitable to graphically represent 3D projections of the complete d...

An Arizona case study consisting of 6 alternative schemes is evaluated with respect to 15 noncommensurable, discrete criteria, using two types of (MCDM) techniques, namely the outranking types of ELECTRE I and II, and the distance-based type of compromise programming (CP). The result is a complete preference ordering of the nondominated alternatives in the cases of ELECTRE II and CP and a parti...

The paper proposes TOPSIS method for solving multi-objective multi-level programming 13 problem (MO-MLPP) with fuzzy parameters via fuzzy goal programming (FGP). At first, λ cut 14 method is used to transform the fuzzily described MO-MLPP into deterministic MO-MLPP. Then, 15 for specific λ , we construct the membership functions of distance functions from positive ideal 16 solution (PIS) and ne...

Sustainable management is a prerequisite for lake to provide range of ecosystem services. The prioritization needs difficult task, especially when the are in conflict and threaten water security. Lake Karla, situated Thessaly plain, Greece, was decimated 1957–1962; due environmental impacts, it later refilled as multipurpose reservoir with high ecological significance. research objective achiev...

The transportation of hazardous materials such as gasoline has unique features due to the nature of these type of materials and the importance role of these material in human life. Therefore, determining the routing of these materials is more challengeable than non-hazardous one due to more dangerous and risky condition besides the transportation costs. Since the distribution of gasoline take p...

This paper presents fuzzy goal programming approach for solving multilevel programming problems with fuzzy parameters. The proposed approach is based on ? -cut and fuzzy goal programming. In the proposed approach, the tolerance membership functions for the fuzzily described objective functions are defined by determining individual best solution of the objective function of every decision maker....

The assessment of economic and environmental sustainability agricultural systems represents a critical issue, which has been addressed in this work with multi-objective programming model to explore the abatement costs (AC) CO2 for set representative contexts Italian arable land agriculture. study was based on FADN-compliant database RICA estimates emissions short time horizon, using linear comp...
