(Points : 5) successors predecessors successors and predecessors followersQuestion 2.2.Project management differs from management of more traditional day-to-day activities because: (Points : 5) it has limited time frame. it has an unlimited budget. it is more expensive. it involves more of the workforce.Question 3.3.Which of the following could not be a linear programming problem constraint? (Points : 5) 1A + 2B 1A + 2B = 3 1A + 2B > 3 1A + 2B < 3Question 4.4.The theoretical limit on the number of constraints that can be handled by a linear programming problem is _____. (Points : 5) 2 3 4 unlimitedQuestion 5.5.Which of the list of items below is not a component of a linear programming problem? (Points : 5) Constraints Objective function Decision variables Nonlinear residualQuestion 6.6.For most graphs, the constraint equations which intersect to form a solution point must be solved simultaneously: (Points : 5) because the solution coordinates from the graph cannot be visually read with high precision. in order to confirm the mathematically determined coordinates. in order to determine all of the optimal point solution. because the slope b and the y-intercept a are not always integers.Question 7.7.For the constraints given below, which point is in the feasible region of this minimization problem? 14x + 6y = 42 x + 3y = 6(Points : 5) x = 2; y = 5 x = 1; y = 2 x = 2; y = 1 x = 2; y = 3Question 8.8.Binary variables are: (Points : 5) 0 or 1 only. any integer value. any continuous value. any negative integer value.Question 9.9.In a 0-1 integer programming model, if the constraint x1 - x2 = 0, it means when project 2 is selected, project 1 ________ be selected. (Points : 5) must always can sometimes can never is alreadyQuestion 10.10.For a linear programming problem, assume that a given resource has not been fully used. We can conclude that the shadow price associated with that constraint: (Points : 5) will have a positive value. will have a negative value. will have a value of zero. could have a positive, negative or a value of zero. (no sign restrictions).Question 11.11.The critical path is the ________ path through the network. (Points : 5) longest shortest straightest most expensiveQuestion 12.12.Elements of project planning include: (Points : 5) defining project objectives. identifying activities to crash. calculating expected times and standard deviations. conducting a "lessons learned" session.Question 13.13.Mallory Furniture buys two products for resale: big shelves (B) and medium shelves (M). Each big shelf costs $500 and requires 100 cubic feet of storage space, and each medium shelf costs $300 and requires 90 cubic feet of storage space. The company has $75,000 to invest in shelves this week, and the warehouse has 18,000 cubic feet available for storage. Profit for each big shelf is $300 and for each medium shelf is $150. If the Mallory Furniture company decides to purchase 150 big shelves and no medium shelves, which of the two resources will be left over? (Points : 5) Investment money only Storage space only Investment money and storage space Neither investment money nor storage spaceQuestion 14.14.A linear programming model consists of: (Points : 5) decision variables. an objective function. constraints. all of the aboveQuestion 15.15.The term refers to testing how a problem solution reacts to changes in one or more of the model parameters. (Points : 5) Priority recognition Decision analysis Analysis of variance Sensitivity analysisQuestion 16.16.If a maximization linear programming problem consists of all less-than-or-equal-to constraints with all positive coefficients and the objective function consists of all positive objective function coefficients, then rounding down the linear programming optimal solution values of the decision variables will ________ result in a(n) ________ solution to the integer linear programming problem. (Points : 5) always; optimal always; non-optimal never; non-optimal sometimes; optimalQuestion 17.17.Decision variables: (Points : 5) measure the objective function. measure how much or how many items to produce, purchase, hire, etc. always exist for each constraint. measure the values of each constraint.Question 18.18.Cully Turniture buys two products for resale: big shelves (B) and medium shelves (M). Each big shelf costs $500 and requires 100 cubic feet of storage space, and each medium shelf costs $300 and requires 90 cubic feet of storage space. The company has $75,000 to invest in shelves this week, and the warehouse has 18,000 cubic feet available for storage. Profit for each big shelf is $300 and for each medium shelf is $150. What is the storage space constraint? (Points : 5) 90 B + 100 M = 18000 90 B + 100 M = 18000 100 B + 90 M = 18000 500 B + 300 M = 18000Question 19.19.Multiple optimum solutions can occur when the objective function is _______ a constraint line. (Points : 5) unequal to equal to linear to parallel toQuestion 20.20.A PERT/CPM activity has an optimistic time estimate of 3 days, a most likely time estimate of 8 days, and a pessimistic time estimate of 10 days. The expected time (in days) of this activity is ____. (Points : 5) 7.0 7.5 8.0 8.5 Rating: 4.9/5
