The ABC Hotel

A small hotel open 24/7 aims at developing a model of its daily operations with the purpose of improving both quality and level of its service. Customers arrive the hotel at random inter-arrival times as shown in the table below:

Table1: Customer Inter-arrival times (Minutes)

These customers fall into two categories: 70% of the customers are daily visitors who wish to use the restaurant and or gym facility and resident customers who intend to only stay overnight (To simplify the modelling process, resident customers intention will not include using of gym or the restaurant).

Upon arrival, daily visitors intend to use either the gym facility (30%) or the restaurant. Length of stay in the gym is Triangle (1,2,3) hour (capacity of 6 people) or Triangle (30,60,90) minute in the restaurant (capacity of 10 people). 22% of the visitors leaving the gym decide to have a quick meal at the restaurant consuming Triangle (20,40,70) minute before leaving the hotel.

For the second type of the arriving customers, resident customers fall into two categories: 84% of residents have already booked ( Advanced booked ) and Non-booked customers. A receptionist allocates resident customers bedrooms with advanced booked customers having priority. The hotel has 6 single rooms and 8 double rooms at the start of operations. 40% of the advanced booked customers prefer single room. The rest of the advanced booked customers prefer double rooms. Length of staying at single bedrooms is estimated to be Triangle (1,2,3) days while the double bedrooms is Triangle (1,2,4) days. Delay at reception (the receptionist process time) is estimated to be Triangle (10,20,40) minute for single bed booking and Triangle (15,20,45) minute for double bed booking.

The non-advanced booked customers will be given an option of waiting for a period of time equal to Triangle (3,4,5) days to be able to offer them a vacant room or to find another hotel (25% is the chance of the first option). The preference of the non-booked customers to book single or double rooms is similar to what advanced-booked customers prefer (same length of staying and room booking preference).

Required:

Write a report that includes:

a. From the perspective of simulation an Introduction to the problem which includes aims, objectives, assumptions, key performance indicators and any other relevant information you deem appropriate.

b. A table showing entities, attributes, activities, state variables, and events.

c. An appropriate flowchart with detailed explanations.

d. Obtain the best fit of the customer arrival-times using Input-Analyser

e. An explanation of which data collection method(s) would be appropriate to capture the required information for modelling this problem.

f. A developed simulation model for 40 customers to imitate the above system (“As-Is” situation). Five simulation runs are required

g. At least two experiments (scenarios) to:

i. Reduce the overall simulation time.

ii. Achieve a reduced queue at each service facility.

iii. Increase the resource(s)/ service facility(s) utilisations.

iv. Reduce average waiting time.

h. A comparison by the use of Excel diagrams of the “As-Is” scenario with the other improvement scenarios.

i. Recommendations for further improvement (bullet points)

j. Appropriate animation in the “As-Is” model you develop is preferred
