Intelligent Machines

Machines that use artificial intelligence to learn from the environment and past experiences to perform better in the presence of variability and uncertainty are called intelligent machines. Intelligence develops according to environment and experience. It is human-like behavior. When the computer system or any programmed machine learns from the inputs and corresponding outputs, it can be called an intelligent machine.

Assume for convenience that demand is constant, the stock keeping unit (SKU) has been stored in k locations of identical size, and all picks are from a single active pick location until that location is exhausted. Then the inventory cycle may be imagined as consisting of k periods, each devoted to a particular pick location. The space utilization in period i is k-(i-1)-12/1 k-i+ k-(i-1) Thus, the average of the space utilization (ASU) of all k periods is asu= (1) The space utilization (SU) of the whole k periods is su = k = k i=1 2 k-i +1 i=1 k-i+ k-i +1 Σk-i+ i=1 k Σ(k-i+1) Use MATLAB® to write the functions to calculate "asu" and "su" of input "K". Employing these functions, program the script to draw the curves that show how both "asu" and "su" increase with additional storage locations, but at a diminishing rate.
Consider a production line that consists of four processes. The sequence of production is Process A, B, C, and D, respectively (A>>B>>C>>D). There is a single machine associated with each process. Assuming that the processing time of each part on each machine takes only 1 minute, then: Calculate the time that the manufacturer needs to produce three parts (red, yellow, and green) in the form of batch production.
A company manufactures three products 1, 2, and 3. Each product requires production time in three departments as shown below: PRODUCT DEPARTMENT 1 DEPARTMENT 2 DEPARTMENT 3 1 3 hr/unit 2 hr/unit 1 hr/unit 2 4 hr/unit 1 hr/unit 3 hr/unit 3 2 hr/unit 2 hr/unit 3 hr/unit There are 500, 400, and 300 hours of production time available in the three departments, respectively. If products 1, 2, and 3 contribute $3, $4, and $2.5 per unit to profit, answer the following questions: (You may attach your solution or write in the box) a) Define the decision variables (2 marks). b) Write all constraints (3 marks). c) Write the objective function (define whether it is a maximization or minimization) (1.5 marks)

It has been observed by management that some faculty members at theuniversity demonstrate a lackadaisical attitude toward teaching. They seldom go to class yet at the end of each month they receive full salary. Management has decided that GHs 200, 300, 400, and 500 will be deducted from a faculty’s salary if he/she offends once, twice, third time and forth time respectively in a month. This means that if a faculty member offends once in a month GHs200 will be deducted, if a faculty member offends twice in a month, GHs 500 (i.e. 200+300) will be deducted, if a faculty member offends three times in a month GHs 900 (i.e. 200+300+400), will be deducted and if a faculty member offends four times in a month GHs 1,400 (i.e. 200+300+400+500). Assuming all faculty members are on a flat salary rate of GHs 2000.a.

Borges Machine Shop, Inc., has a 1-year contract for the production of 75,000 gear housings for a new off-road vehicle. Owner Luis Borges hopes the contract will be extended and the volume increased next year. Borges has developed costs for three alternatives. They are general-purpose equipment (GPE), flexible manufacturing system (FMS), and expensive, but efficient, dedicated machine (DM). The cost data follow: Annual contracted units Annual fixed cost Per unit variable cost General-Purpose Equipment (GPE) 75,000 $100,000 $18.00 Flexible Manufacturing System (FMS) 75,000 $250,000 $14.50 Dedicated Machine (DM) 75,000 $500,000 $13.00
A company wants to plan production for the ensuing year to minimize the combined cost of production and inventory costs. In each quarter of the year, demand is anticipated to be 130, 160, 250, and 150 units, respectively. The plant can produce a maximum of 200 units each quarter. The product can be manufactured at a cost of $15 per unit during the first quarter, however the manufacturing cost is expected to rise by $1 per quarter. Excess production can be stored from one quarter to the next at a cost of $1.50 per unit, but the storage facility can hold a maximum of 60 units. How should the production be scheduled so as to minimize the total costs? Please answer using python Formulate an LP model to minimize costs. Solve the LP (provide exact values for all variables and the optimal objective function).
