Integrated watershed management is required to ensure the reasonable use of resources and reconcile interactions among natural and human systems. In the present study, an interval fuzzy multiobjective programming (IFMOP) method was used to solve an integrated watershed management problem. Based...

To date, most methods for direct blockmodeling of social network data have focused on the optimization of a single objective function. However, there are a variety of social network applications where it is advantageous to consider two or more objectives simultaneously. These applications can...

This study investigates the tradeoffs among different uses of forests in the Swedish mountain region, where several interest groups use the forests for different and conflicting objectives. The tradeoffs information can help the involved interest groups to reach a rational compromise on the...

This study analyzes the economic effects of environmental concerns in forest management in the Swedish mountain region. The environmental concerns include the amount of deadwood, the area of broad-leaved forest, and the area of old growth forest. The analyses are performed by formulating a fuzzy...

Integer linear fractional programming problem with multiple objective MOILFP is an important field of research and has not received as much attention as did multiple objective linear fractional programming. In this work, we develop a branch and cut algorithm based on continuous fractional...

This paper explores the tradeoff options for optimal coastal land use in Krabi’s coastal land development zone (CLDZ). Maximizing the net private benefit and maximizing the net environmental benefits, subject to the constraints set by land availability, effluent discharge from shrimp farms,...

Despite the mathematical properties and algorithmic features of an interactive method, that method's success usually lies in the kind of information it requires from the decision maker. In some cases, this information constrains the decision maker. If she does not find it easy and comfortable to...

To remedy challenges resulting from a high number of objectives in multiobjective programming and multicriteria decision making, this paper chooses to decompose the vector objective function and characterizes the relationships between solutions for the original problem and the collection of...
