- Case studies and modeling of logistics systems are the basis for the formulation of the content and structure of a reference model for the organization and management of Value Networks as a higher stage of integrated development of supply chains. The definition of a mathematical model for the balance of the Value Network can reveal the characteristics and principles of organization and management of Value Networks.The instrument obtained enables supply chains to assess their level of development and identify the characteristics that should be developed to reach the concept of Value Network, which is based on knowledge development and environmental integration as supports of the same and its competitive position in the global market.Proper integration into the model of environmental factors ensures that Value Networks are inserted into the objectives of promoting sustainable development. The current concept of logistics flow is extended to incorporate within it the exchange of energy, resources and impacts to the environment.The research methods used were based on a combination of study and experimentation of cases and the conceptual and mathematical modeling of systems.

- The development of supply chain management includes the capacities coordination among the processes that integrate it, so much in the operative plan as in the strategic one. This problem could be allocated to the classic job shop scheduling problems of the Operations Research. In such direction, a second generalization of the calculation algorithm of the production, logistics and service capacities is formulated starting from the one reached previously by the own authors. With this generalization it is facilitated to carry out the calculations of capacity at the supply chain level and of each one of the processes. The generality's application is flexible to processes of production, transport, storage, administration and for service. The capacities of each process of the supply chain are expressed in the magnitudes of the final demand of products and services in the consumer, considering the losses and returns along the supply chain. A study case is presented to demonstrate the possibility of use in one field, but it is explained the possibility to use in different fields, from the production of aluminum carpentry to services related to medical equipments.

- Due to the low presence of edible oil in hard-currency stores in 2006 and the need of knowing their actual demand in the Cuban market, it became necessary to undertake a study of the levels of availability of this product. This study was performed to measure the availability of this product in a phase of implementation of the Model. The study was divided into two stages, a first one that discusses the availability of oil in the country with all the commercial chains and a second one that focuses on Havana and Commercial Chain TRD Caribe. In the first stage the level of availability was high (90,8%), while in the second stage availability levels dropped significantly to 45,84%. The levels of availability are analyzed in various stages of the supply chain, showing that there are large differences in levels of availability in the same period of time for different actors in the supply chain, which leads to the conclusion that there are problems in the organization of the logistics of the edible oil supply chain, which generates low levels of availability meaning low levels at customers service.
