The linear Bilevel Programming Problem (BLP) is an instance of a linear hierarchical decision process where the lower level constraint set is dependent on decisions taken at the upper level. In this paper we propose to solve this NP-hard problem using an adaptive search method related to the Tabu Search metaheuristic. Numerical results on large scale linear BLPs are presented.

Sequencing is the most impact factor in many production areas, such as assembly lines, batch production, Travelling Salesman Problem (TSP), product sequences, process etc. The flow and analysis from one item to another can be presented by square matrix which number of rows or columns equal manipulated items, this special form called “From-To matrix”. suffers drawbacks when it applied determine ...

an interactive heuristic approach can offer a practical solution to the problem of linear integer programming (lip) by combining an optimization technique with the decision maker’s (dm) judgment and technical supervision. this is made possible using the concept of bicriterion linear programming (blp) problem in an integer environment. this model proposes two bicriterion linear programs for iden...

Many gluten-free products are deficient in amino acids, especially essential acids (EAA). Therefore, the incorporation of additives rich free (FAA) into can be a promising strategy to alleviate certain symptoms celiac disease associated with EAA deficiencies. This study aimed evaluate effect broccoli leaf powder (BLP) mini sponge cakes (GFS) on profile FFA. BLP replaced an equivalent amount (2....

Applied researchers most often estimate the demand for differentiated products assuming that at one item can be purchased. Yet simultaneous multiple purchases are pervasive. Ignoring interdependence among lead to erroneous counterfactuals, in particular, because complementarities ruled out. I consider identification and estimation of a random coefficient discrete choice model bundles, namely se...

This paper introduces a general multi-layer storage structure. Object instances from geographic surface objects are transferred and stored into the standard structure. We introduce some new access control rules to modify the BLP model, so that the owner can process unrestrictedly an object that is created by the owner. When a process needs to decide whether to execute an object method, it calcu...

Whilst few studies have explored royalty negotiations for build, operate and transfer (BOT) projects, some works have proposed numerous royalty formulas to evaluate royalty amounts or franchise fees for a BOT project. Despite this, the royalty negotiation process is one of the many critical negotiation items of a concession contract. This study not only developed a royalty negotiation model for...
