Abstract

This project is about the application of AHP and TOPSIS in the conceptual design selection process of hospital beds. Generation of ideas in producing a hospital beds are crucial since it need a precise consideration based on its important criteria. The design of hospital beds has improved over the years based on patient type of illness and to gives a user friendly product to the caregiver and nursing staffs. The conceptual design selection of hospital beds was focused on electronic types of medical beds used in a standard ward. The main objective of this project was determine the best conceptual design using integrated AHP-TOPSIS method by identified the important criteria in order to design a hospital beds. The conceptual design is based on proposed concept that has been generated based on customer requirement. There are five different conceptual designs of existing hospital beds was developed as alternatives of this conceptual design selection. AHP is used to determine the weight of the selection criteria. Follows with TOPSIS that is used to perform the ranking of alternatives which is the proposed concept. The integration of AHP and TOPSIS method was proven as one of the successful method in multi-criteria decision making processes because of the systematic evaluation between criteria and alternatives. Based on the result from the five different conceptual design of hospital bed, Design Concept 3 was selected as the best alternatives based on its performance to the requirement. The ranking of TOPSIS shows the same after the analysis of AHP in the Expert Choice software. The main and specific objectives for of the project were achieved. As a conclusion Design concept 3 is the best conceptual design of hospital bed and has the highest percentage priority value compared to other alternatives which is 30% using integrated AHP-TOPSIS approach.
