LECTURE 22. Course: “Design of Systems: Structural Approach” Dept. “Communication Networks &Systems”, Faculty of Radioengineering & Cybernetics Moscow Inst. of Physics and Technology (University) Mark Sh. Levin Inst. for Information Transmission Problems, RAS Email: mslevin@acm.org / mslevin@iitp.ru PLAN: 1Hierarchical Morphological Multicriteria Design (HMMD): Application to system improvement (transformation, upgrade, adaptation) 2.System evolution / development: Example for several generations of software DSS COMBI-PC 3.Example for complex system analysis and design (modeling, analysis, & design of modular system): (a) system modeling, (b) system comparison, (c) revelation of bottlenecks, (d) system design, (e) system upgrade, (f) modeling of system generations.

Application example 1: Design of team Team: S = L*R*M*D S1=L3*R3*M3*D3 Leader Researcher Manager Designer R L M D L1(2) R1(2) M1(3) D1(3) L2(3) R2(3) M2(3) D2(3) L3(2) R3(1) M3(2) D3(1)
Application example 1: Design of team Team: S = L*R*M*D S1=L3*R3*M3*D3 M3(2) L3(2) IMPROVEMENT ACTIONS: 1.New member 2.Improvement of member 3.Improvement of compatibility 4.New structure D3(1) R3(1)
Application example: Improvement of team Plan for improvement S = A * B * C S1=A3*B1*C2 S2=A3*B1*C3 New members Trips & communication Professional courses A C B A1(2) B1(1) C1(2) A2(2) B2(2) C2(1) A3=A1&A2(2) B3(1) C3(1) B4(1) C4=C1&C3(3) B5=B3&B4(2) B6=B1&B4(3) B7=B1&B2&B4(3)
Design alternatives for improvement of a team A1 new leader A2 new manager A3 = A1 & A2 B1 course on advances in science & engineering B2 course on foreign language B3 course on system analysis B4 course on creativity B5 = B3 & B4 B6 = B1 & B4 B7 = B1 & B2 & B4 C1 course on human relation C2 joint trip to rest-home C3 joint participation in professional conference C4 = C1 & C2
Improvement of system Improvement (change) system Members (DA’s) Compatibility New structure New members (DA’s) Improved members (DA’s)
Improvement of system SYSTEM IMPROVEMENT PROCESS: 1.Improvement / Upgrade 2.System change (e.g., development / evolution) 3.System transformation 4.Adaptation (including on-line adaptation)
Hierarchical design of system improvement DESIGN OF A COMPOSITE IMPROVEMENT PLAN : Ideal Point Pareto-effective points w=3 w=2 w=1 DISCRETE SPACE OF QUALITY: N(S) = ( w(S); n1(S) , n2(S) , n3(S) )
