The manager of a regional warehouse must decide on the number of loading docks to request for a new facility in order to minimize the sum of dock costs and driver-truck costs. The manager has leamed that each driver-truck combination represents a cost of $224 per day and that each dock plus loading crew represents a cost of $1,166 per day Use Table 18.4. 0. How many docks should be requested if trucks arrive at the rate of four per day, each dock can handle five trucks per day, and both rates ate Poisson? b. An employee has proposed adding new equipment that would speed up the loading rate to 571 trucks per day. The equipment would cost an additional $100 per day for each dock. What is the lowest daily total cost that can be achieved with the new equipment? (Round your cost omount to 2 decimal ploces and all other calculations to 3 decimal places.)
