5.6. Chasov parametri ta optimizіcіya sіtyових графиіків

Yaksho shlyah not critical, then vin reserve for an hour , a kind of yaq rіznitsya mіzh dovzhinoyu critical shlyahu і tom, scho rozglyadayatsya. Він показує, на скільки у сумі може бути збільшена тривалість всіх робіт, що належать цьому шляху. Звідси it is possible зробити висновок, що кожна з робіт шляху на його ділянціі, що not zbіgаєє з з з critical shlachom (we will close між duma подіями critical шляу), має reserve hour.

The reserve for an hour of robotics is shown, the hour can be transferred to the site for the hour of the day, the robot for the name, but the term does not change the complex of robots.

The reserve for the robot's hour is the maximum reserve for the robots, and passes through the dan to the robot. Tsey reserve mozhna vikoristati at vikonannі danoї robot Yakscho її Pochatkova Podiya zdіysnitsya in samy rannіy termіn, i mozhna dopustiti zdіysnennya kіntsevoї podії in Yogo samy pіznіy termіn.

It is important for the authorities to maintain the safety of the clock for robotics, so that they do not depend on the robot, but on everything, and pass through them. In the case of a temporary reservoir, one hour for one day, a reservation for an hour or more, but to lie on the maximum route will be completed. Reserve the hour of robots, but lie on the least (not the maximum in trivalous) shah, but pass through the qiu to the robot, to speedily follow the amount of the vichoric reservoir.

Інші reserved hour robot є parts of the її storage tank.

Really at the practicality of the triviality of the robot, the actual їхній стан mууть змінювася. When you can change the time of the day, the hour of the day, the end of the robot and the critical route. I know the critical path, kerivnitstmo zoesereditysya on the quiet robots, scho є virishalnimi z poglyad termnіnі zakіchenchenya vsyіh robіt.

Pіslya znahodzhennya critical high road, rezervіv hour robіt i otsіnki іmovіrnostі vikonannya project tasks termіn guilty Buti conducts vsebіchny analіz sіtovogo grafіka i priynyatі come in for yogo optimіzatsії. Tsei doslilivy etap in rozrobtі sitiovyh grafіkіv rozrivaєe basic ідею СПУ. Він полягає in the reduced сітьового граіка у відповідність із specify the terms and opportunities of the organization, the project is divided.

Optimumizatsiya sitiogovogo gorikіka in izolozhnosti vіd povnoti rozv'yazvani задачh problem Mozhoboti is naturally expanded to private and complex. The forms of private optimization of the official county є: мінімізація hour виконання комплекссу робіт при заданій його вартості; Mіnіmіzіcіya vartostі complex of robots at the given hour of the project. Complex optimization is the most important feature of the optimal solution of the values ​​of the terms and conditions of a project in a project, in particular, in the yogic realiza- tion.

Optimizatsiya sіtovogo gornіka is represented by the process of filling in the organi- zation of the complex to the complex of uraуuvannâm terminu yogo vikonannya. Optimization is carried out with the method of speeding up a critical shlyakh, a national resource of resources.

At Pershu chergo priymayutsya go for speedy trivalovisty robot, scho on the critical shlyahu. Access:

? pererozpodіlom usіh vidіv resursіv, yak timchasovih (vikoristannya rezervіv hour uncritically shlyahіv), so i manpower, materіalnih, energetichnih at tsomu pererozpodіl resursіv Iti guilty, yak usually іz zones Mensch napruzhenih, at Zoni, scho poєdnuyut naybіlsh napruzhenі robots.

Napriklad, mozhna zbilshiti zmіnnіst robot on the "vuzkih" dilyankah budivnitsva. Tse zahіd naybіlsh efektivny, oskilki permissibility to get away from the result of the resultant quiet machines (excavators, verstaties, etc.), tilki zbіlshivshi chiselnіst robіnikіv.

? Short-term labor for critical criticism for the process of transmitting part of the robot to the shlykhs, but to reserve the hour;

? By a look of topology, by the warehouse of the robot and the structure of the land.

? Zabezpechiti spent parallels (spoluchenih) robot;

? Розділити wide front робіт на більш дрібні зони або ділянки;

? Zmenshiti trivalval progamy mozhna shlyom zmіni zastosovuvanoi tehnologii, napriklad, u budivnitstvі, zamenoi monolitnyh zalizobetonnikh stroitіі birnimi elements, scho vygodovlyayutsya na zavodi.

Provodyachi koriguvannya grafіka mother required on uvazі scho robіtnikіv zabezpechuyut resources to viznachenoї mezhі (CCB dwellers Leather robіtnik zabezpecheny dostatnіm front robіt i MAV mozhlivіst dotrimuvatis rules tehnіki BEZPEKA).

In the process of speedy trivalovysti robot critical steps can interchange, and nadalі process optimizatsiї bude sverznavaniy na srekochennya trivalovisti robyt new critical shlyahu і so budu prodovzhuvatis to oderzhannya zadovilnogo result. In ідеалі довжина кожного з повних шляхів може стати рівною довжині кричного шляху або принаймні шляху критичної зони. Todi all robots will be conducted in the spring, and the terminus completed by the project will quickly flow.

At the practical level, when the effec- tive sex is sold, the plan is put into effect dostatochno before the endings of the factor vartosty robot. The project can squeeze prisokorennya yogo vikonannya, scho, naturally, vіdіb'ється на вартості: вона збільшиться. Tom neobhidno viznachiti optimally spivvidnoshennya mizh vartisticu project i trivalistyu yogo vikonannya.

With the vikoristannym method "hour-vartist" pripuskayut, sho zmenshenny trivalosti robot proporazcino zrostanju її varmosti. Zrostannia vartosti at the changed hour is called vitraty on prisokorennya.

In daniy hour on pravitcі dimzhu spochatku koreguyut per hour, tobto bring її to the desired term zakinchennia budivnitsva. Potim proceed to koreguvannya gorik for criterie rozpodilu resursiv, pochinauchi z trudovikh resursiv.

Varto vіdznachiti, scho at lіnіynіy zalezhnostі vartostі robіt od їhnoї trivalostі task pobudovi optimal sіtovogo grafіka Mauger Buti yak sformulovana task lіnіynogo programuvannya have yakіy neobhіdno mіnіmіzuvati vartіst vikonannya project at obmezhennі on au-Perche, trivalostі kozhnoї robots have vstanovlenih furrows, and, Therefore Friend, trivalov, be-yakogo povnogo shlyayu sitiovogo gorikika not bilsh established by the term vikonannya project.

Otzhe, methods sіtovogo planuvannya i upravlіnnya zabezpechuyut kerіvnikіv i vikonavtsіv on vsіh dіlyankah robots obґruntovanoyu іnformatsієyu scho neobhіdna їm for rіshen of acceptance by planuvannyu, organіzatsії i Control. And in the case of the VCOR, the SPU is not just one method of planning, but an automated method of controlling the vibronic process.
