Model Penentuan Nilai Target Functional Requirement Berbasis Utilitas

Abstract

Abstract:In a product design and development process, a designer faces a problem to decide functional requirement (FR) target values. That decision is made under a risk since it is conducted in the early design phase using incomplete information. Utility function can be used to reflect the decision maker attitude towards the risk in making such decision. In this research, we develop a utility-based model to determine FR target values using quadratic utility function and information from Quality Function Deployment (QFD). A pencil design is used as a numerical example using quadratic utility function for each FR. The model can be applied for balancing customer and designer interest in determining FR target values.Keywords: Optimization, quadratic utility, risk, functional requirement. PendahuluanSebuah produk dirancang dan dikembangkan untuk memenuhi kebutuhan dan keinginan pelanggan. Produk tersebut harus dibuat dengan tetap menjaga kualitas pada biaya yang kompetitif. Quality Function Deployment (QFD) banyak digunakan untuk membantu perancangan, pengembangan, dan perbaikan produk berdasarkan voice of customer (Fung et al. [3]

The Urban Car Body Design for “Energy Efficient Car Contest 2019” using Quality Function Deployment

“…A product is designed and developed to meet the needs and desires of customers. The product must be made with an emphasis on quality at a competitive cost [27]. The Quality Function Deployment (QFD) is a product development system starting from the product design, manufacturing process to the product reaching the consumers.…”
