  8. Decision Variable • The decision to be made is how many times to use each medium. The decision variables are: DTV – number of times daytime TV is used ETV - number of times daytime TV is used DN - number of times daytime TV is used SN - number of times daytime TV is used R - number of times daytime TV is used

  9. Objective Function • Objective –To maximize the total exposure quality units for the overall media selection plan. • Objective Function Max Z = 65DTV+90ETV+40DN+60SN+20R

  10. Constraints • Availability of Media DTV<=15 ETV<=10 DN<=25 SN<= 4 R<=30

  11. Budget Advertising budget is not more than $30,000 1500DTV+3000ETV+400DN+1000SN+100R<=30000 • Television Restrictions DTV+ ETV >=10 1500DTV + 3000ETV <=18,000

  12. Customers Reached 1000DTV+2000ETV+1500DN+2500SN+300R>=50000 • Non-Negativity DTV,ETV,DN,SN,R>=0

  13. MARKETING RESEARCH

  14. Introduction • Market research is conducted to learn consumer characteristics, attitudes and preferences. • Market research firms include designing study, conducting market surveys, analyzing the data collected and providing summary reports and recommendations.

  15. QUESTION • Market survey,Inc (MSI), specializes in evaluating consumer reaction to new product, services and advertising campaigns. A client firm has requested MSI’s assistance in ascertaining consumer reaction to a recently marketed household product. During meetings with the client, MSI agreed to conduct door-to-door personal interviews to obtain responses from households with children and households without children. In additional, MSI agreed to conduct both day and evening interviews. Specifically, the client’s contract called for MSI to conduct 1000 interviews under the following quota guidelines:

  16. Interview at least 400 households with children. • Interview at least 400 households without children. • The total number of households interviewed during the evening must be at least as great as the number of households interviewed during the day. • At least 40% of the interview for households with children must be conducted during the evening. • At least 60% of the interviews for households without children must be conducted during the evening.

  17. Because the interviews for households with children take additional interviewers time and because evening interviewers are paid more than the daytime interviewers, the cost varies with the type of interview. Based on previous research studies, estimates of the interview costs are as follows:

  18. What is the household, time of day interview plan that will satisfy the contract requirements at a minimum total interviewing cost?

  19. Decision Variables • DC = No of daytime interviews of households with children. • EC= No of evening interviews of households with children • DNC= No of daytime interviews of households without children • ENC= No of evening interviews of households without children.

  20. Objective Function Min 20DC+ 25 EC + 18DNC + 20ENC

  21. Constrain 1 “the client’s contract called for MSI to conduct 1000 interviews” DC+ EC + DNC + ENC + 1000

  22. Constrain 2 • Interview at least 400 households with children. • DC+ EC >= 400

  23. Constrain 3 • Interview at least 400 households without children. • DNC + ENC >= 400

  24. Constrain 4 • The total number of households interviewed during the evening must be at least as great as the number of households interviewed during the day. • EC + ENC >= DC + DNC • -DC + EC -DNC + ENC >= 0

  25. Constrain 5 • At least 40% of the interview for households with children must be conducted during the evening. • EC>= 0.4( DC + EC ) or • -0.4DC + 0.6 EC >= 0

  26. Constrain 6 • At least 60% of the interviews for households without children must be conducted during the evening. • ENC >= 0.6 ( DNC + ENC ) or • -0.6 DNC + 0.4 ENC >= 0

  27. Non Negativity DC ,EC ,DNC ,ENC >= 0
