Hi, I need to maximise revenue on 40+ services in portfolio which are split into two categories. In these categories, there are two restrictions: One category, consisting of approx. 25 products can increase by 1.5%, overall; The other category with the remaining 15 products can increase by 2.5%, overall. These represent the lagrange constraints. The percentages are indicated on the equations below. The evolution in sales volumes determines a mix of "correct" augmentations of prices. A price augmentation of a badly performing product in the first category of 2% for example, will percentually leave less room for another product to increase, respecting the overall increase of 1.5%. We know a price increase on that product leaves less room to increase prices of other products in our portfolio. At the same time we know that if this product is declining in sales, there are better products to which to allocate the increase in order to maximize revenue. I have the equations which show product volume evolution over time and I want to increase the price on the correct products (thus not those product with declining sales volumes) in order to maximise revenue. If you can solve, please indicate which method you will use. Some simplified trend equations for the different products with their restricitons (the percentages are behind the equation): Evolution sales t = 1…96 Restriction GB=1407265.91 + t * -161.42 1.50% WB=275265.3 + t * 616.89 1.50% JB=-83119.94 + t * 5551.65 1.50% BDp=30416.63 + t * -98.43 1.50% BDt=10368.8 + t * -46.98 1.50% BE=2059155.22 + t * -29871.29 1.50% TH=152.17 + t * -1.54 1.50% SeB=183511.65 + t * -30.2 1.50% KC=47908.91 + t * -4.33 1.50% GP=50062.41 + t * -307.34 1.50% RP=39681.92 + t * 138.94 1.50% TTK1=45169.25 + t * -73.42 2.50% TTK3=5162.09 + t * 5.41 2.50% TTK12=11703.82 + t * 1.42 2.50% HaT=11958.24 + t * -15.16 2.50% ST1=25923.53 + t * -48.15 2.50% ST3=7184.74 + t * 0.2 2.50% ST12=4977.21 + t * 20.79 2.50% Ca=77292.98 + t * -49.36 2.50% NT1=112.62 + t * 0.21 2.50% NT3=25.37 + t * -0.01 2.50%

I have a PhD degree in computational physics and extensive knowledge and experience in math, statistics, numerical methods, including optimization. I've done hundreds of projects in numerical methods, Matlab and Python, please see reviews on my profile. Given that all trends are linear, objective function and the Lagrange constraints are linear, too, I think this can be solved by means of linear algebra or linear programming. I'd try linear algebra first (a matrix formulation). Of course there are other optimization methods at my disposal if the first two don't work for some reason. FYI, I own a small consulting business registered in the state of Illinois. You could pay me as an individual freelancer or as a business, whichever suits you better.

Hello, how are you? I hope you have a bright day/evening from your side. I have read the details provided, but please contact me so that we can discuss more on the project. I believe I have the required skills in this case. I will work on your requirements personally since I do not outsource to third parties, this guarantees you high-quality work that is delivered on time. You can also request for revisions till you’re fully satisfied with the work. I believe, coding, designing, programming writing is a passion and not a money making business where people will deliver low-quality work just to get paid. Try my services, and you will never regret. Waiting for your kind response
