This paper presents a framework for the modeling and analysis of business model designs involving a network of interconnected business entities. The framework includes an ecosystem-modeling component, a simulation component, and a serviceanalysis component, and integrates methods from value network modeling, game theory analysis, and multiagent systems. A role-based paradigm is introduced for characterizing ecosystem entities in order to easily allow for the evolution of the ecosystem and duplicated functionality for entities. We show how the framework can be used to provide insight into value distribution among the entities and evaluation of business model performance under different scenarios. The methods are illustrated using a case study of a retail business-to-business service ecosystem.

Abstract. So far most stowage planning only consider the stowage of single type containers or do not consider the stability of the containership. Here a 0-1 linear programming model for this problem is proposed. The objective is to maximize space utilization while minimize the operation cost from upload and download of different types containers at each port of a multi-port journey, with vessel stability, industry regulations and customized rules as the constraints. Based on experiments by adopting branch & cut algorithm from COIN-OR(Common Optimization Interface for Operations Research) to such model. Successively, a simulation system is developed to verify the feasibility and practicability of the model. By using the branch and cut algorithm of COIN-OR, the simulation system has shown that our model is efficient and robust.
