Concluding Remarks

• Phase-II of CASDE is configured as a period for consolidation and sustained overall growth.

• It is viewed as a time during which CASDE would– Achieve Core Competences through Generic Studies

– Develop Applications through Focused Activities

– Create Awareness & Disseminate New Knowledge

– Act as a SDE Facilitator to User/Interested Agencies

• Phase-II of CASDE is also characterized by its efforts to seek a suitable partnership with other agencies within, as well as outside of, DRDO.

• We, at CASDE, see our future as an ARDB COE, yet requiring only a minimal support from ARDB.

Generic Activities – Within Purview of CASDE Phase-II

Focused Activities – To be proposed as separate projects to interested user/funding agencies

Awareness Creation in Phase-II   CEP-1: “Optimization in Engineering Design”, 2-day course.   CEP-2: “Multi-disciplinary Design Optimization”, 2-Day Course.   CEP-3: “Integrated Product & Process Development”, 5-day course   CEP-4: “Applied Mechatronics”, 3-day course, including lab.  CEP-5: “Modelling & Simulation in Engg. Systems”, 3-day course.

MSO-DMES is of Aeronautical Society of India and CASDE would play a supporting role in organizing this.
