  1. Broadcast Programming: Techniques & ABC’s Weekly Lineup Andrew Gonzalez Eli Levin Morgan Strauss

  2. ABC’s 2010 Fall Schedule

  3. Scheduling Strategies • Lead-off • Lead-in • Hammocking • Block Programming • Tent-Poling

  4. Lead-off Lead-in Hammocking Block Programming Tent-Poling

  5. A18-49+ • A18-49+ = 100*(shows average rating/league average) • Key: • 0-69: flop • 70-99: marginal • 100-124: solid • 125-149: hit • 150-199: big hit • 200+: megahit • For Friday: • 60-74: solid • 75+: hit

  6. Our Problem • P6 | prec,dj,wj | maxj (A18-49+) -> maxt,d (A18-49+) • prec: Dancing with the Stars • Performance show must be broadcasted before the results show • pj: Duration of shows (1,2,4) • wj: A18-49+ rankings • *Heuristic Based Objectives

  7. Machine Environment • P6: M1, M2, M3, M4, M5, M6 • Parallel Machines Sunday through Friday, respectively

  8. Machine Environment Diagram

  9. Constraint Set • prec, (rj), dj, wj • Precedence Constraint • See: Dancing With The Stars • Lead-In • Release/Due Date • all shows due by 11 • Weighted on A18-49+

  10. Variable Objective • See Algorithm for Pure Programming • Variability of Objectives • Overall Viewership • Promote specific shows • others • How do we achieve these? • With different heuristic approaches conditioned off of our base algorithm

  11. Our Scheduling Heuristic 1. Create an empty 6x6 matrix with starting times 1-6 (8:00-10:30) on the columns & days 1-6 (Monday-Sunday) on the rows 2. Create the set Shows containing all aired shows in 2010-11 & the set Slots containing all available slots in the matrix 3. Sort all shows in descending order by 2010-11 A18-49+ rankings 4. Sort all time slots in descending order by historical A18-49+ rankings 5. Set j: the next highest ranked show in Shows & set (t,d): the next highest ranked slot in Slots 6. If j has a precedence constraint Do Steps 7 & 8 together for j and jprec maximizing the sum of A18-49+ rankings for both feasible time slots If there is no room for j and/or jprec according to its precedence constraint Delete the lowest ranked show(s) from a feasible time slot for j and/or jprec Add the deleted show(s) back to Shows and any remaining time back to Slots 7. If t + pj <= 6 & (t,d) thru (t+pj,d) is NOT already scheduled Schedule show j in slots (t,d) thru (t+pj,d) in the matrix Remove show j from Shows & remove slot (t,d) thru (t+pj,d) from Slots 8. If (t+pj,d) is scheduled already Set the iterative variable (t,d): next highest ranked slot in Slots Go back to Step 6

  12. Ranking Time Slots & Shows

  13. Our Schedule for ABC’s Weekly Lineup

  14. ABC’s Lineup vs. Our Heuristic

  15. Going Forward • Implement scheduling strategies into our heuristic • Lead-off: early due date • Lead-in: precedence constraint • Hammocking: precedence constraint (other variations exist as well) • Block Programming: precedence constraint, scheduling on same machine • Tent-Poling: release time-due-date combination
