Master in Engineering Design

1. Master in Engineering Design Air Conditioning Active Distribution System Cinema Case Study Decision Analysis (DA) José Gaspar 5 January 2005 ACADS Decision Model

2. Problem Description • Cinema closed without a renovating project defined; • Cinema intervention in the air conditioning system; • Cinema future decided on the beginning of this year; • Alternatives presented by the cinema owner: • Maintain the three rooms; • Split the area in to a big room and a smaller one; • Return to the original project (one single room). ACADS Decision Model

3. Decision support • Propose an innovating air conditioning system, which: • Reduce exploring costs; • Increase cinema appeal to the public; • Serve as a marketing due to his innovation abilities: • Excellent reaction time to occupancy changes; • Low energy consumption; • Thermo experience of the room; ACADS Decision Model

4. Multicriteria Methodology • Characterization of the decision context • Definition of screening and evaluation criteria ACADS Decision Model

5. Multicriteria Methodology • Introduction of the options on the MACBETH model. ACADS Decision Model

6. Multicriteria Methodology • Construction of a descriptor of impacts for each evaluation criterion • Definition of descriptors of plausible impacts; • Definition of levels of reference “Good” and “Neutral”; ACADS Decision Model

7. Multicriteria Methodology • Construction of a descriptor of impacts for each evaluation criterion • Building value functions; Qualitative descriptor for the air distribution balancing (FPV) ACADS Decision Model

8. Multicriteria Methodology • Construction of a descriptor of impacts for each evaluation criterion • Building value functions; Matrix of qualitative judgements (Air distribution balancing) ACADS Decision Model
