There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 4 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $400, E is $415 and all other activities is : $100 (per week per activity). The crashing cost, second week and onwards(crashing second time), for activity A is $1000 per week, E is $1200 per week and for all other activities is $200 per activity per week. You have a maximum crashing budget of $2505. The maximum possible reduction in the project duration will be:
a. 2 weeks
b. 3 weeks
c. 4 weeks
d. 5 weeks
e. 6 weeks
A professor has been contacted by four not-for-profit agencies that are willing to work with student consulting teams. The agencies need help with such things as budgeting, information systems, coordinating volunteers, and forecasting.
Although each of the four student teams could work with any of the agencies, the professor feels that there is a difference in the amount of time it would take each group to solve each problem. The professor's estimate of the time, in days,
is given in the table below.

The city and county have been geographically segmented into areas containing 5,650 residences. The police recognize that not all crimes and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,170 of the 5,650 residences for data on crime. (Respondents are guaranteed anonymity.)

- CRUISE MINI CASE: Sunshine Cruise Lines is a cruise operator that offers three- to seven-day cruises along five Caribbean routes. It has developed a reputation as a party cruise operator and the majority of its revenue comes from vacationing college students. This type of customer demand is highly cyclical, and Sunshine finds that repeat purchase is high while its consumers are in college, but practically disappears after graduation. In an effort to encourage its customers to continue taking Sunshine Cruises after they have graduated, the cruise operator has begun offering Adventure Cruises, with port stops on islands known for eco-tourism and biodiversity, both on land and off shore, appealing to young professionals who like to hike and scuba dive or snorkel. In contrast to its party cruises, Sunshine focuses its marketing message for Adventure Cruises on activities at port stops and the convenience of being able to explore several Caribbean destinations from the comfort of a single…arrow_forwardThe capacity of the Internet to accommodate two distinct types of application support services remains uncertain.

The company is looking to expand its activities by opening 3 new branches in Lebanon. To facilitate information and data sharing, the company decided to implement a network in each branch, then to connect all the branches into a single network. Also, the new network will be based on giving employees the facility to use their laptops and smartphones in most of their operations. On the other hand, the company has a major problem with organizing its data. The human resource, finance, sales, and customer service departments have all developed separately their own systems and data files, which created a lot of redundancy and poor security. Managers can't have access to timely, accurate, or relevant information for analysis because the data have been poorly organized and maintained in separated files. The main concern for the company, regarding this problem, is to discover new and hidden patterns of customers'…arrow_forward
