Solved in 2 steps
- why does long trip length is usually less elastic with respect to the attributes of thetransportation system than short trip length?A construction company has an opportunity to submit a bid for the construction of a new apartment building. From the specification provided by the developer, the PERT network along with the three-time estimate (in a week) for each activity is shown in figure-1. Determine:a) Critical path and its standard deviation?b) Probability of completing the work in 38 weeks?c) Completion time duration for which the company should bid to provide 95% probability of completing the work in time?is the following true / false / maybe ? " in transportation problem , shipments can occur between any two transshipment nodes.
- Financial data of a highway construction project is given . You are questioned to develop a plan such that both cost and project duration would be at optimum status. A,C,E,H are the activities that have no float. Office rent $ 50/- per day Bills $ 30/- per day Miscellaneous expenses $78/- per dayWhat is the purpose or the function of the following:- Problem definition 2. Trip generation 3. Trip distribution 4. Alternative evaluationDiscuss in details the best practices of asset management strategy in transportation.
- Assume the following project data given in Table 2. It is required to crash the project duration from its original duration. Assume Indirect (overhead) costs are $120 per day. Draw the network diagram by using AON method Calculate the normal duration and Normal project cost Least-cost and optimum point/durations for the project. Show the relationship between time and cost Graphically.

- The _____ for an activity is the amount that its duration can slip without causing the project to be delayed. a. Speed b. Float c. Stride d. PaceA work-mode-choice model is developed from data acquired in the field in order to determine the probabilities of individual travelers selecting various modes. The mode choices include automobile drive alone (DL), automobile shared-ride(SR), and bus (B). The utility functions are estimated as: UDL = 2.6 – 0.3(costDL) – 0.02(travel time DL) USR = 0.7 – 0.3(costSR) – 0.04(travel time SR) UB = –0.3(costB) – 0.01(travel time B) where cost is in dollars and time is in minutes. The cost of driving an automobile is $5.50 with a travel time of 21 minutes, while the bus fare is $1.25 with a travel time of 27 minutes. How many people will use the shared-ride mode from a community of 4500 workers, assuming the shared-ride option always consists of three individuals sharing costs equally?Decisions Recognizing Risk The construction time for a highway project depends on weather conditions. It is expected to take 240 days if the weather is dry and the temperature is hot. If the weather is damp and cool, the project is expected to take 320 days. Otherwise, it is expected to take 275 days. The historical data suggest that the probability of cool, damp weather is 35% and that of dry, hot weather is 40%. What is the expected completion time?
