Certain markets evoke popular discomfort, distrust and even outrage. Trade in arms, drugs, toxic waste, child labor and body parts, for example, elicits these reactions to different degrees. This paper asks—what is it about some markets that brings about these responses? It is argued that three key parameters—extremity, agency and inequality—have a bearing on our intuitive reactions and serve t...

We study the mechanism design problem of a social planner for locating two facilities on line interval [0, 1], where set n strategic agents report their locations and determines facilities. consider requirement minimum distance 0 ≤ d 1 between Given are heterogeneous, we model cost/utility an agent as sum his distances to both In heterogeneous two-facility location game minimize cost, show that...

In this paper, we propose the planar obnoxious facilities p-median problem. problem objective is to find p locations for that minimize weighted sum of distances between communities and their closest facility. version, add constraints each facility must be located at least a certain distance from partial set because they generate nuisance affecting these communities. The resulting extremely non-...

Incomplete contracts and inadequate enforcement of labor rights, together with the asymmetry power between a worker her employer, create an environment where employer can forcibly extract additional services (e.g. unpaid overtime or sexual favors) from beyond mutually agreed terms exchange. We show that coercive impositions co-exist voluntary transactions in labour market, positive incidence co...

We consider an obnoxious facility location problem in which the facility is a trajectory consisting of a bounded length polygonal chain of two edges having extremes anchored at two given points. In other words, given a set S of points in the plane and a positive value l0, we want to compute an anchored 1-corner polygonal chain having length at most l0 such that the minimum distance to the point...

In this paper, a new model for the semi-obnoxious facility location problem is introduced. The new model is composed of a weighted minisum function to represent the transportation costs and a distance-based piecewise function to represent the obnoxious effects of the facility. A single-objective particle swarm optimizer (PSO) and a bi-objective PSO are devised to solve the problem. Results are ...

Taste is mainly a function of taste buds in the mouth. In the formulation for pediatric & geriatric, bed ridden & non-cooperative patients the main challenge to the compounding pharmacist is to mask the taste of obnoxious and bitter drugs, result is patient not receiving the optimal therapeutic value of their medication. Taste masking is the main factor in the development of the dosage form. It...
