3.4. Optimization of marketing models

Optimal tasks in economics are to name economical and mathematical problems, the values ​​of which are the values ​​of the best (optimal) positiveness of the active criterion (criterias) of the resource of resources. Virishuyutsya soi tasks for the use of optimizatsynyh models mathematical methods programvannya.

On the basis of the balance models, optimize the model of the crisis , the problems of the economy, the problems of the future, the crisis for the vibor, the functional functions, the selection of the values ​​in the areas of the pripustimih rishen. The principle function in the fatal vigil is to be interpreted as a threefold moment: by kerovaniem zmіnnimi, nekorovymi parametres (scho lie, napriklad, vіd zvnіshnogo srednerischa), and the formation of deposits by them (function visibility). Yakshco cognate the criterion of optimality through U , kerovani zmіnnі - X , parametr - R , set interi (region) zmіni keroviyh zmіnnih - through M , then zagalny vyglyad optimizatsynoi model such as:

(3.1)

The tasks of the curriculum (3.1) are determined by the methods of mathematical programming, including the linear programming, the nonlinear programming, the dynamic programming, the programming, and so on. The method of mathematical programming for the optimization tasks is to be defined by the visibility of the functions, the obmen, Scho viznachayut region M , і spetsialnymi obmezhenni on kerovani zmінні (наприклад, вимогою щодо їх цілочисельності). Problem solving (3.1) is called optimally optimal Pishennyam, pod optimal plan.

Significant part of the economical tasks, in addition to the number of marketing galleys, will require a small-scale settlement, if the zmіnnі values ​​mean kіlkіst nepodіlnyh oditnіs produkіії, obladnannya tochno. In a number of ways to solve these problems, vikorishvuyut vikoristannyam zvichaynih metodіv, naprikladnom simplex, z obal'shimi rounded up to tsilikh numbers abo Gomory for the linear tasks of the program.

• Bagato tasks marketing to be developed in the process of economical and mathematical modeling before the optimization models. Розглянемо деякіTYи задач.

Static model of the optimization of the access to the posts. The basic mathematical model of the optimal prikriplennya spizhivachchiv before postavtchiliv є so called the transport problem of linear programming

• The task of the comic explorer. In the tasks of the business consultant, you can find the route in this way, turn all the visated points, turn back to the shortest term, or with the lost vitrates on the roads.
• The task of rozmіschennya warehouse. The problem of the rozmіschennya warehouse є odnієyu o optimizіzicnykh zadachi dosleniya operatsіy i virishuyutsya zvichayno by methods of non-linear programming. The task of the field is in the minimization of transportation and storage volumes of such wastes:
• З кожного підприємства має бути відвантажена all products;
• Not in the same way as the intermittent crowded warehouse;
• Має бути задоволені мовлення всіх споживачів.

In the process of rozv'yana zadachi znachit'sya optimal for a minimum of vitrits trichlennaya kombinaciya: pidpriemstvo-warehouse-spizhivach. For active minds, the task of procuring warehousing can be addressed to zichaynoy transport problems and linear programming.

The task of the rancher (about the backpack). Tse problem about naykraschy vibire object viz zagalnoi їх kіlostі such a rank, shob somarnna vaga (abo gabariti) in foreign subjects did not overload the given values, abo sumarnaya korisnіst chi іnsha zagalna otsіka (kіlkіst kalorіy, zagalna vartіst і т. Д.) Була максимаю. The problem of the ranch is rooted in the task of the small-scale linear program, the methods of dynamical programming and the latter methods. Zokrema, the task is to be cautious when planning the optimal reserve of ships, ships, warehouses, and so on.
