The paper presents the process of the selection of a potential supplier, which have to be the most appropriate to stakeholders. The selection is based on a set of criteria: Delivery Price, Financial Position, Production Specifications, Standards and Relevant Certificates, Commercial Strength, and the Performance of supplier, etc. The criteria for evaluation and their importance are selected by taking into consideration the interests and goals of the stakeholders. The solution of problem was made by applying a new Additive Ratio ASsessment (ARAS) method with the grey criteria scores – ARAS-G method. The proposed technique could be applied to substantiate the selection of effective alternative of sustainable development, impact on environment, structures, technologies, investments, etc.

We have studied the design documentation for two industrial software modules to see if they apply ideas corresponding to contracts, as introduced by Bertrand Meyer, either in an intuitive or in a formal way. They did not, and we identified this fact to be a potential risk factor. This paper presents one of the modules studied, consisting of a sequence of switching sections. Starting from this case study, the paper also discusses how switching sections in general can be designed using contracts in order to increase the semantic integrity of the module as a whole.
