A computational model for inventory management and planning

Ayub, Mehar; Ahsanuddin, Muhammad - Volkswirtschaftliche Fakultät, … - 2000

The objective of the study is to determine the factors of the optimal level of merchandizing inventory. The study is based on a mathematical model. The results revealed some interesting findings. The most important conclusion is that the 'Usage of Material' or the Sales Volume is not the real...

Variational optimization of probability measure spaces resolves the chain store paradox

Gagen, Michael; Nemoto, Kae - Volkswirtschaftliche Fakultät, … - 2006

. This optimization method requires that players adopt a particular type of probability measure space. Here, we introduce … optimization methods to locate novel equilibria. These variational methods can reconcile game theoretic prediction and observed … human behaviours, as we illustrate by resolving the chain store paradox. Our generalized optimization analysis has …

The Impact of New Capital Requirements on the Portfolio Decisions of Finnish Pension Institutions

Sjöholm, Hans-Kristian - Hanken Svenska Handelshögskolan - 2007

This paper examines the potential impact of new capital requirements on asset allocations of Finnish pension institutions. We describe the new requirements and consider portfolio construction to minimize regulatory capital, given the investor’s preferred level of expected return. Results...

A mispricing model of stocks under asymmetric information

Buckley, Winston S.; Brown, Garfield O.; Marshall, Mario - In: European Journal of Operational Research 221 (2012) 3, pp. 584-592

We extend the theory of asymmetric information in mispricing models for stocks following geometric Brownian motion to constant relative risk averse investors. Mispricing follows a continuous mean-reverting Ornstein–Uhlenbeck process. Optimal portfolios and maximum expected log-linear utilities...

Adoption of logistic principles in WOODY-biomass energy clusters

Tegla, Zsolt; Hagen, Istvan; Hollo, Ervin; … - In: Review of Applied Socio-Economic Research 4 (2012) 2, pp. 236-246

Applying logistics principles within production technologies is not an objective or not even a magic potion. It is a tool for getting and maintaining some competitive advantage. This is true in the case of production technology of arboreal biomass for heating purposes too. The produce is not...

Comparison of Mean-Variance and Exact Utility Maximization in Stock Portfolio Selection

Amilon, Henrik - Nationalekonomiska Institutionen, Ekonomihögskolan - 2001

In the early 50's, Markowitz introduced the modern portfolio selection theory which, to this very day, constitutes the basis of many investment decisions. Given different correlated assets, how does an investor create a portfolio maximizing the expected utility? Markowitz's contribution was to...

The Economics of Manure Utilization: Model and Application

Keplinger, Keith O.; Hauck, Larry M. - In: Journal of Agricultural and Resource Economics 31 (2006) 02

A model of manure utilization is developed and applied to four types of transportable manure. Model results highlight important response differences among manure types and generally illustrate the diseconomies of manure production. For example, as manure production increases, manure value...

Grid Business Models for Brokers Executing SLA-Based Workflows

Quan, Dang Minh; Altmann, Jorn - Technology Management, Economics and Policy Program … - 2010

In the Grid Computing environment, many users need the results of their calculations within a specific period of time. Those users are willing to pay for getting their work completed on time. However, this requirement must be agreed on in a Service Level Agreement (SLA) by both, the user and the...
