quality function development (qfd) is a planning tools used to fulfill customer expectation and qfd is a systematic process to translating customer requirement (whats) into technical description (hows). qfd aims to maximize customer satisfactions related to enterprise satisfaction. the inherent fuzziness of relationships in qfd modeling justifies the use of fuzzy regression for estimating the r...

We propose a method, e3-service, to reason about satisfying customer needs (problems stated by the consumer) by means of a bundle of multi-supplier service bundles (solutions from specific suppliers). The e3-service method represents customer needs, desired consequences by the customer, and the services that realize those consequences in a multi-perspective service catalogue. This catalogue is ...

In order to design new services in e-mobility, the knowledge of customer needs is crucial. In this paper, we compare the results from a literature review about customer needs with the results from harvesting a modern data source: micro blog data.

We consider a G-network with Poisson flow of positive customers. Each positive customer entering the network is characterized by a set of stochastic parameters: customer route, the length of customer route, customer volume and his service length at each route stage as well. The following node types are considered: (0) an exponential node with cn servers, infinite buffer and FIFO discipline; (1)...
