CLASS A

Group Assignment (max 4 students per group) Write down member’s name, NPM, and class in the upper right corner. Deadline : UTS PTLF 1. An ABC Company has establish a nine-digit coding scheme to distinguish between various types

of parts. The six part types coded are given below. Each code digit is assigned a numeric value between 0 and 9.

Part 1 : 112171213 Part 2 : 112175427 Part 3 : 112174327

Part 4 : 102173203 Part 5 : 112175327 Part 6 : 412174453

a. Find the Minkowsky absolute distance between the parts! b. Using the hierarchical clustering algorithm construct the dendogram for parts! c. Identify two part families by defining a suitable threshold value! d. Find the Hamming distance metrics between the parts!

2. For the classification code of six parts in Problem no.1, use the multi-objective approach to form

two part families. The classification code prioritized sequence vector Z = {5,9,3,4,2,1,6,7,8} and the set of digits of significant similarity z = {5,9}. Identify the optimal sequence in which the parts are arranged in each part family!

3. Apply the ROC and DCA method to the matrix below and identify the part families and machine groups. Compute grouping efficiency and grouping efficacy for each method!

4. A part requires three processing steps on two machines in the sequence A-B-A. the demand for

this part is 10.000 units per year. The company operates six days per week, eight hours per day. Give the following performance data, find the number of each machine needed to meet the demand.
