Graph – 4.6 Total costs on development of the software product
On this graph we can see that main part of costs are connected with
developers salary.
Expected cost of the software product:
Cpp = Ssum * Kn.pr ; (4.34)
Cpp = 161008,94* 1,08 = 106093,8 tenge;
These, calculations show that the cost of development and upgrades of the electronic textbook on discrete mathematics
constitutes = 106093,8 tenges.
5 LABOR PROTECTIONS AND INDUSTRIAL ECOLOGY
5.1 General information on enterprise labor protection
By the reason that any room will be suitable for work with the electronic textbook as an example one of IITU offices is taken. On the average work the 40th hour per week. Indoors there are 15 computers. The area of the room is 54 sq.m. height there are 3,2 m. Power supply = 220B, 27 electric sockets (sockets). Irradiating = 24 fluorescent lamps of a ceiling arrangement =6*4, 2 ventilating extracts, 1 video recorder, electro supply machine gun of 1 piece. Heating = 1 conditioner and 1 batteries fankoil. All wires are isolated, protected with the help a channel cable. In all building about 600 pieces are established. In the room there is 1 piece everything, are calculated in each audience according to a room quadrature. On the average 1 piece is calculated on 20 sq.m; 30 sq.m; 50 sq.m; In audience 1 which is calculated on 50 sq.m. As the audience makes 54 sq.m.
5.2 Analysis of dangerous and harmful production factors
Production factors can influence the person in the course of his work dangerous (defiant injuries) and harmful (defiant diseases).
Harmful production factor – the production factor, which influence on working, in particular conditions, leads to a disease or decrease in serviceability.
Dangerous production factor – the production factor, which influence on working, in particular conditions, leads to a trauma or other sudden deterioration of health.
Harmful production factor, depending on intensity and influence duration, can become dangerous.
On a workplace the following dangerous and harmful production factors were established:
• the increased noise level on a workplace;
• the raised level of electromagnetic radiations;
• absence of natural light;
• poor illuminating intensity of a working zone;
