"Don't Bother Me, I Can't Cope" 2018 Andy Chu, owner of a small electronic module assembly shop located in Hong Kong, had just signed a contract that would require increased production of two types of sub-assemblies produced in the shop. The shop would supply these sub-assemblies on a JIT basis to a large consumer products company. He announced this happy news to the supervisors of these assembly lines and asked them to come up with a plan for meeting the new requirement. The present production rate from Line A, supervised by Ms. Alice Feng, was 315 units/day. Under the new contract, 420 units/day needed to be supplied. The estimated contribution per unit was 116 HK$, and the line was currently staffed by seven workers. Sub-assembly A required 16 different activities. Technological relationships between the activities and the time required to do each activity are given in the table below. The technological relationships establish the precedences between the activities. For example, activity 4 cannot be started until activity 1 is finished, and similarly, activity 7 cannot be started until activities 4 and 5 are finished.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
