Changes in a Service Oriented Enterprise: A Game Theory Approach

Abstract
Service Oriented Enterprises (SOEs) are subject to constant change and variation. In this paper, the changes are considered from an economic perspective based on service culture notion. Once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. We construct a game theoretic model trying to capture the possible conflicting interests of different parties in a SOE. Three incentive mechanisms are applied to the model. The first incentive mechanism shares the utility equally among the services involved in the change the second utility-sharing rule is based on the Nash’s bargaining solution, which accommodates the possible biased interdependencies inside the network and the third rule, based on the Harsanyi’s modified Shapley value, takes into account the possible coalition formation among the network parties. Since the three rules are analytically solvable, the principles of utility sharing can be implemented, for instance, as ex-ante contracts.

Abstract
The production of food-grade salt from crude solar salt has been examined through a techno-economic evaluation. This study aimed to investigate a salt factory to analyze its technical and economic aspects to determine the precise parameters for improving the quality of food-grade salt. The primary process of this factory involves grinding, washing, draining, drying, and fortification, supported by equipment like brine management, conveyors, sieves, and packaging. The proposed salt plant, designed for a 3-ton daily output over 15 years, requires 30 months for construction and a 4-month startup. The total capital outlay is USD 1,921,000, with USD 310,000 for technology and equipment. Economic indicators, including a Net Present Value (NPV) of USD 7,862,000, an Internal Rate of Return (IRR) of 46.48%, payback in 1.56 years, and a Return on Investment (ROI) of 64.28%, demonstrate feasibility. Establishing a salt plant in Indonesia supports food-grade salt production, stabilizes solar salt prices and enhances the welfare of traditional salt farmers. Ultimately, the results of this study can provide valuable insights for evaluating the feasibility of establishing a food-grade salt production plant in Indonesia.
