In this article a single machine time-dependent scheduling problem with total completion time criterion is considered. There are n given jobs j1, . . . , jn and the processing time pi of the i-th job is given by pi = 1 + bisi, where si is the starting time of the i-th job, i = 1, . . . n. If all jobs have different and non-zero deterioration rates and bi > bj ⇒ bi ≥ bmin+1 bmin bj + 1 bmin , wh...

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

Academic and practitioner literature reports on numerous Business Intelligence (BI) challenges. Spohrer states that knowledge discovery and knowledge application are two sides of the same coin where both sides are needed for value to emerge. Aligned with this, we identify that the failed emergence of BI value – typified by the prevalence of BI challenges – results from a myopic focus on produci...

In recent years Business Intelligence (BI) systems have consistently been rated as one of the highest priorities of Information Systems (IS) and business leaders. BI allows firms to apply information for supporting their processes and decisions by combining its capabilities in both of organizational and technical issues. Many of companies are being spent a significant portion of its IT budgets ...

in this paper, a location allocation (la) problem in construction and demolition (c&d;) waste management (wm) is studied. a bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control c&d; waste and the after tre...

Bulk rhombohedral Bi at ambient pressure is a well-known semimetal, and its transition to a superconductor has not been observed, at least down to 50 mK. We report that, unlike bulk rhombohedral Bi, granular Bi nanowires with well-defined rhombohedral grains of approximately 10 nm diameter, fabricated by electrochemically depositing Bi into porous polycarbonate membranes at ambient pressure, ar...

The scavenger receptor class B type I (SR-BI) was the first molecularly well-defined cell-surface HDL receptor to be described. SR-BI mediates selective HDL cholesterol uptake by formation of a productive lipoprotein/receptor complex, which requires specific structural domains and conformation states of apolipoprotein A-I present in HDL particles. SR-BI is abundantly expressed in several tissue...
