Assume that orders for suits have been listed in the above table in the order in which they were
received.
Your team has been assigned to complete 10 client projects over the next two months. These
projects and their processing times (time taken to complete a project once started, in days) are
described in the table below. In addition, each project has a due-date that has been set by your
internal marketing team so that the customers will be delighted with your service if you complete the
project by the due-date. However, your team has only enough resources to pursue exactly one
project at any given time. Once started, a project is worked through its completion and is not
interrupted. As a result of the sequence in which you choose to handle projects, each project will
either be on time, or late if it is completed past the due date. If a project is late, the amount of time
by which it misses its due-date is called its tardiness. The objective is to pick the sequence in which to
complete the projects so as to minimize the total tardiness in the schedule.
What is the minimum total tardiness…

When people are moving from one home to another they contact Easy Moving to take care of relocating all of their belongings. The people responsible for the move are the Drivers/Movers. Because driving a truck is an essential function of the job, individuals must not only be physically capable of driving, but also must have an impeccable driving record.

- Codeword Codeword is a medium-size firm that designs and manufactures electronic systems for the mass transit industry. It competes with other firms to win contracts to provide such systems. When Codeword receives a contract, it creates a project to complete the work. Most projects range from $10 million to $50 million in cost and from one to three years in duration. Codeword can have 6 to 12 projects going on at any one time, in various stages of completion—some just starting and others finishing. Codeword has a handful of project managers who report to the general manager; other people report to their functional manager. For example, the electronics engineers all report to the manager of electrical engineering, who reports to the general manager. The functional manager assigns particular individuals to work on various projects. Some people work full-time on a project, whereas others split their time among two or three projects. Although individuals are assigned to work for a project…arrow_forwardBE Spreadsheet Mike Reynolds has four assignments due in class tomorrow, and his class times are as follows: Time 9 a.m. 12 p.m. 2 p.m. 5:30 p.m. Each class lasts one hour, and Mike has no other classes. It is now midnight, and Mike estimates that the marketing, finance, psychology, and OM assignments will take him one, four, five, and seven hours, respectively. Assume that all time till the last class begins can be spent on completing assignments but each assignment should be done till the time of the class on the same subject. (Mike can prepare assignments for the next classes during previous classes.) Use the Excel Sequencing template to determine how he should schedule the work. Use minus sign to enter negative lateness values, if any. Enter the half an hour value as 0.5, e.g., 3:30 p.m. should be entered as 15.5. If your answer is zero, enter "0".

Jean has more than 10 years of experience as a wealth manager and strong, long relationships with several clients. Most of his clients are based in the Middle East. Jean is eager to start onboarding clients and is putting pressure on his new employer to cut corners and simplify the process. He argues that the onboarding process should be automatic since the clients already held accounts with his previous employer – a US bank with offices in London – so Jean’s previous employer had already reviewed the clients’ information and profiles. Furthermore, and in order not to waste time, Jean says that he should be allowed to informally manage the portfolios of his clients which are still held with his former employer until the clients are fully onboarded. Discuss the approach of John in the context of regulatory guidelines and professional standards.arrow_forward
