An operations analyst at a large casual dining restaurant chain is developing a restaurant simulation model. An empirical analysis of check data revealed that the most common party size at lunch time is typically 2, and that parties greater than 8 are rare. In the restaurants, customers arrive to the restaurant in groups and are seated at the first available table that is large enough to seat the group. Which of the following distributions is most appropriate for modeling the input variable 'party size? a) b) 0.4 0.3+ 0.2+ 0,1+ 0 1...... 03- 03 T d) 0.25- 02 0.15+ 0.1 0.05 D 210123 Distribution d) O Distribution b) Distribution a) Distribution c) !1. 02- 01+ Given the following demand and forecast values, calculate the corresponding Cumulative Error.
