The impossibility of describing measurement in quantum mechanics while using a mechanical model for the machine, remains one its central problems. Objective collapse theories attempt to resolve this problem by proposing alterations Schroedinger's equation. Here, we present minimal an objective theory that, contrast previous proposals, does not employ state dependent stochastic terms constructio...

The complexity of power systems is increasing as new generating units are added to in order supply the growing economies. This has resulted further research into generator maintenance scheduling (GMS) problem which seeks ensure optimal preventive that effective and reliable. focused on developing a schedule using tri-objective model. GMS model solved two solution methodologies. first an exact m...

Mobility, safety, and environmental sustainability are priorities in the geometric design of roundabouts. This paper presents a multi-objective optimization model that determines elements single-lane roundabouts using all three objectives. The user can specify weights for objectives, or determine optimal weights. Mobility is defined terms roundabout delay modeled United Kingdom empirical model....

in this paper, the researchers present a multi-objective linear fractional inventory model using fuzzy pro-gramming. the proposed method in this paper is applied to a problem with two objective functions. the re-sulted fuzzy model is transformed into an ordinary linear programming. the implementation of the develop-ing model presented in this paper is demonstrated through the use of some numeri...

Vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. Previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. This paper presents a bi-objective mathematical mod...
