We analyze the problem of optimal location of a set of facilities in the presence of stochastic demand and congestion. Customers travel to the closest facility to obtain service; the problem is to determine the number, locations, and capacity of the facilities. Under rather general assumptions...

In this study, we consider the joint economic lot sizing problem (JELP) under stochastic demand. Almost all of the literature on JELP assumes that the demand is deterministic and constant with very limited exceptions. We indicate the shortcomings of the work in the literature in this regard, and...

Economic environmental dispatch (EED) is a significant optimization problem in electric power system. With more wide spread use of wind power, it is necessary to include wind energy conversion system (WECS) in the EED problem. This paper presents a model to solve the EED problem incorporating...

In this paper, we develop a unified mixed integer linear modelling approach to compute near-optimal policy parameters for the non-stationary stochastic lot sizing problem under static–dynamic uncertainty strategy. The proposed approach applies to settings in which unmet demand is backordered...

We consider a classical heavy tailed risk model, included in a regulation mechanism. The regulator exercises a minimal cash requirement level and penalties for violating it to regulate the insurance firm. The problem of the insurance firm is to establish an investment and risk exposure policy as...

This paper presents the effect of implementing interruptible loads (ILs) from the demand side for reserve allocation in an electricity supply system. A unit commitment (UC) objective function is used to incorporate the energy/reserve providers and to schedule energy and reserves simultaneously....

This study applies the Sequential Panel Selection Method (SPSM) to investigate the time-series properties of provincial house prices for entire, large, medium, and small middle-segments of South Africa. Quarterly time-series data were collected from nine provinces in South Africa for different...

The goal of this paper is provide a theory of K-person non-stationary Markov games with unbounded rewards, for a countable state space and action spaces. We investigate both the finite and infinite horizon problems. We define the concept of strong Nash equilibrium and present conditions for both...

Climatic conditions and weather play an important role in production agriculture. Using district level panels for 42 years from India and dynamic panel estimation procedure we estimate the impact of weather risk on cropping intensity. Our non-stationary and dynamic panel model results suggest...

The goal of this study was to analyze the impact of a newly introduced market information system “E-Soko”, on beans markets integration by comparing the period before and after the system was implemented in Rwanda. Beans, both bush and climbing, are the most important traded crop in rural...
