## Analytically minimize operational costs, equipment cost and to short payback period of investment

Fixed-Price - Intermediate (\$\$) - Est. Budget: \$250 - Posted
Looking for experience industrial engineer or specialist in operation research to solve minimization problem. Background: This work aim is to minimize operational costs, equipment cost and to short payback period of investment. Scope of work: 1. Analytically solve the model (marked with yellow), which means to show which optimal S1 and S2 minimize the PBP while taking in consideration the constraint. If it is required- show convexity, linearity and infinity of the functions. * 2. Analytically show and explain in which scenarios of minimum PBP: S1<S2, S1>S2, S1=S2.* 3. Optional (or should be priced separately): To write MATLAB code for demonstrating by sensitivity analysis both operational and capacity planning stages: a. The whole equations for operational stage will be supplied, including excel file with all indexed "i" parameters (8760 hours in one year). Those parameters should be imported to MATLAB to matrix. b. Graph 1: Sensitivity analysis for "hi" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps (i.e 0.7h, 0.8h…1.3h) influences on the annual production by sub-system 1 and by sub-system-2 "X1, X2". c. Graph 2: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the production hours "i" of isubsystem-1 and isubsystem-2. d. Graph 3: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the payback period. e. Graph 4: Sensitivity analysis for "h" values: to check on the operational stage how the values of "hi" 0.7-1.3 by 0.1 steps influences on the equipment capacity S1 and S2. f. Graph 5: Sensitivity analysis for "hi" values: to check on the operational stage how the values of "h" 0.7-1.3 by 0.1 steps influences on the savings . *every step should be shown with explanations and any math phrase should be typed by "Math type".

## Scanning Electron Microscope (SEM) to generate an image

Fixed-Price - Expert (\$\$\$) - Est. Budget: \$200 - Posted
The Scanning electron microscope is an instrument which helps to generate an image for any specimen in the micrometer ranges. The electron beam strikes the specimen which will generate secondary electrons. These secondary electrons will generate an analog current through the detector designed and will generate an image using conversion techniques.

## Need math expert to write code to find best way to split objects

Hourly - Expert (\$\$\$) - Est. Time: 1 to 3 months, Less than 10 hrs/week - Posted
I have a group of objects which reside in a rectangular shape. I want to split this rectangular shape into smaller shapes which can be irregular. The splits can only occur in the white part of the image. I want to be able to set a min and maximum cut size. I want to have the least amount of shapes. A line would need to be drawn where the splits occur.
