Every inventory system requires answers to two basic questions:
when to order and how much to order.
In this paper we have described and compared four alternate
methods for obtaining the answers for these two questions. Four different
types of demand distribution during the lead time are considered:
normal, exponential,...
Adapting man, as an organic link, to closed loop control
systems, is increasingly presenting problems to designers of
systems of any nature. Performance of the human in the systems
is dependent upon a multitude of recognized factors, and
many as yet unknown factors and variables.
In order to investigate the...
The purpose of this investigation is to explore research management
problems pertaining to types of research where direct outputs are
in terms of intangible ideas or the kind of knowledge which takes years
to be proven applicable or economically fruitful.
The study was based on the analysis of the more...
In this study the ability of establishing time standards using the
technique of regression analysis is demonstrated. Numerical standards
are developed for fish filleting operations which are satisfactory for
practical use by the seafood processing management.
For the analysis non-experimental or historical fillet data was
obtained from two seafood processors...
This paper approaches the problem of arranging
facilities and moving materials in a sheltered workshop,
or rehabilitation center, employing handicapped people.
Traditional plant layout and material handling principles,
along with human engineering principles, are used for
developing a layout for Open Door Incorporated, a
sheltered workshop located in Corvallis, Oregon....
network technique as a common tool of communication between the
information user (e. g. manager, accountant) and the model builder
or management scientist as well as between the systems analystprogrammer
and the management scientist is examined.
The premise is that the discrepancy between an information
system and a decision model...
The study evaluates performances of three multiple time series
(MTS) forecasting methods; investigates possible improvements in
MTS forecasting operations, and proposes a multiple time series
based forecasting system. Time series considered are finite,
linear, covariance stationary, and discrete.
Specific objectives for the thesis were: (a) conducting comparative
studies of MTS...
In this paper, we discuss extensions of two coordinated ordering
methods which reduce inventory costs for multi-item systems.
Goyal's method, which is useful for constant demand, decreases cost
by assigning an order interval for each item, and an optimum number
of purchase orders per period. Goyal's method is modified to...
Proteins are the metabolic machines of the cell and as such, the study of proteins could illuminate the dominant biological activities that are occurring within cells and reveal how an organism interacts with its environment. Here, we used proteomic techniques to study the abundant marine bacterium SAR11 both as an...
