Analyzing of office satisfaction level by using fuzzy cognitive map

Fuzzy cognitive map (FCM) can successfully show knowledge and human experience, presenting concepts to show the necessary elements and the cause-effect relationships among the concepts to model the behavior of any system. FCM consists of a number of nodes, representing variables, factors, states, observables, etc., of the modeled system, and of causal relationships among the nodes. This paper purposes to analyze the office satisfaction level, which handles office environment quality, sick building syndrome, and musculoskeletal complaints, by using fuzzy cognitive map. Office environment quality includes temperature, humidity, noise, lighting and air quality. Musculoskeletal complaints include neck, shoulder, arm, wrist, waist and leg. Sick building syndrome includes eye, noise, throat, skin and headache. These criteria and sub-criteria interact each other to other. These interactions are considered by using FCM. The defuzzification method is used to transform to crisp numbers from fuzzy numbers. An aggregation operator can be used to aggregate the judgments of three experts in group decision making environment and the unique judgment is acquired
