The article presents a decision model based on customers' satisfaction to select partners in the supply chain. The first stage of the model is to use DEA to select high efficiency according to enterprises' inside factors. The second stage is to analyze the cooperation in order to select the perfect partners using a goal-programming model to minimize customers' satisfaction. An example is given to illustrate the model.
The problem of achieving near‐optimality in homogeneous central‐server queueing networks is investigated by means of a composite approach based on approximate operational analysis and goal programming procedures. A ...

Climate change causes range shifts of species and habitats, thus making existing reserve networks less suitable in the future. Existing optimisation procedures hence need to be adapted in order to account for changes in the spatial distribution of habitat types as well as their relative occurrence. We develop a multi-objective optimisation procedure that considers these dynamic changes. We demonstrate the functioning of the model by applying it to a conceptual case study. In this case study, we aim to gain an understanding of the consequences of not adapting the reserve network despite climate change and the optimal adaptation pathways for different funding levels. Finally, we consider whether larger flexibility in terms of when to adapt the reserve network by providing a one-off discounted payment instead of regular payment improves the outcome achieved. We find that the optimisation procedure is suitable to identify adaptation pathways as the outcome is improved, especially for habitat types that become increasingly threatened. Initially providing a one-off discounted payment instead of regular payments leads to higher habitat protection. In order to facilitate future research, we provide the code of the optimisation on request.

Promotion is a form of corporate communication that uses various methods to reach a targeted audience with a certain message in order to achieve specific organizational objectives. This promotional mix consists of a blend of advertising, personal selling, sales promotion and public relations tools. An advertising decision is primarily influenced by the choice of media, media budget etc. especially if the advertising is required to be done in a segmented market. Therefore an optimal advertising media selection is a strategic factor for the advertising of products in different market segments as each segment is consumer specific covering homogenous group of potential consumers with similar needs and wants. In this paper media selection model is developed to facilitate the advertising media selection process for multiple products that need to accommodate different market segments. The problem is solved through goal programming technique. A real life example from Indian business industry has been taken to validate the results.
