Shourian Department of Civil Engineering, Amirkabir University of Technology (Tehran Polytechnic), Tehran, Iran E-mail: [email protected] A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project’s firm energy yield. Particle swarm optimization (PSO) i...

This paper develops two models to study the impact of outsourcing on wage inequality between skilled and unskilled labor in the developed country and the developing country. The first model assumes symmetric production technologies in both countries, and predicts that outsourcing will increase wage inequality in the developed country, but decrease wage inequality in the developing country. The ...

In this paper, we formulate a firm’s investment in a production facility with maximum capacity and outsourcing strategy. Existing literature of capacity choice results in an explosive capacity and long delay in investment. Actually, there are slight possibility that a firm installs a facility with an explosive capacity, instead, a firm can outsource production when the demand exceeds its capaci...

Reliability based optimization (RBO) is one of the most appropriate methods for structural design under uncertainties. It searches for the best compromise between cost and safety while considering system uncertainties by incorporating reliability measures within the optimization. Despite the advantages of RBO, its application to practical engineering problem is still quite challenging. In this ...

The paper examines possible reasons behind expanded outsourcing by modeling outsourcing decisions when intellectual property rights are imperfectly protected. Firms in the North develop higher quality levels of existing products and then decide whether to shift some stages of production to the South. Production in the South lowers costs but entails risk of imitation by Southern firms. In this s...

This paper models the choice between outsourcing and integration for a firm that faces price uncertainty in both the upstream and downstream market. The firm can outsource the production of some input at an exogenous, stochastic price or it can produce the input internally at an average cost of production that is U-shaped. Up to three different production regimes can arise: pure outsourcing, pu...

Symbiosis means the intimate living together of two dissimilar organisms in a mutually beneficial relationship, or a cooperative relationship. IT-outsourcing and off-shoring is momentarily far from a symbiosis. This proposal is meant to understand how sourcing can become true symbiosis between the involved parties, hence the name of our proposal. The importance of IT-outsourcing increased signi...

Information systems (IS) outsourcing relationships are determined by uncertainties and changing business environments for both client and vendor over a long-term outsourcing lifecycle. Although IS outsourcing arrangements have been widely researched, little attention has been paid to how changing business circumstances and resulting customer demands can be systematically assessed, considered, a...

Information technology outsourcing relationships between clients and suppliers are generally embedded into formal contracts. The empirical literature on contracting usually assumes that contractual completeness is difficult to achieve due to the transaction costs of describing—or of even foreseeing—the possible states of nature in advance. Little research has been done on the on-going set of pr...
