In an earlier study [1, pp.407-415] it was assumed that a
linear production function would be the best to depict the relationship
between wheat production and explanatory variables in the Punjab. After
a careful scrutiny, four of the explanatory variables, viz., area under
Mexican Wheat varieties, area under local wheat, fertilizer application
and rainfall, were employed to explain varia¬tions in wheat production.
As this linear relationship gave a good fit, it was claimed that the
equations, derived from 1967-68 to 1971-72 output and input data, can be
useful in forecasting wheat production in the Punjab for future years
well in advance of actual wheat harvests and, in fact, a forecast of
wheat production in the Punjab for 1973-74 was published [2, pp.
106-112], based on the findings of that model. Whether the linear
production function related the dependent and inde¬pendent variables in
the best possible manner was not tested. The results of our analysis in
the present paper indicated that the re-specification of the
rela¬tionship will be of little use.1 In addition, in an earlier model
the rainfall relevant to wheat production was defined as the total
rainfall during the months of November-January of each wheat season.
Publication of the article con¬taining that model elicited suggestions
that use of seven-month rainfall from July to January (instead of
three-month rainfall used in the model) might improve the results of the
model. Accordingly, it was decided to test that model using

AbstractA model is developed for planning optimal production and employment levels in multi‐product, multistage production systems. The market requirements for each product over the planning period are given. Backorders and/or shortages are permitted. Backorders and shortages must be considered in order to determine the amount of each product's demand that should be filled, backlogged, or go unsatisfied if the production capacity is insufficient to fill all market requirements. Backorders and shortages, on the other hand, are desirable under certain dynamic market conditions.

There is now a very extensive literature on the subject of professions. There is, moreover, the frantic activity of members of those occupations concerned with production, such as production engineering and work study, to lay claim to the title — professional. Yet no one seems to have examined in any detail whether production would benefit or not if such occupations were professionalised. This paper offers some preliminary thoughts on the problem. First the nature of professions is examined; secondly, the field of production; thirdly changing trends in the world of work, within which production and those associated with production are located; finally some conclusions on the place of the professions in production are offered.
