The need for protein or the amount of needed by fish sector in Indonesia has never been recorded and known. Although demand aquatic feeds is very high, data related to requirements feed be known determining urgency providing substitutes feed. So, it necessary predict based on a series production data. This study predicted Nile tilapia (Oreochromis niloticus). Three exponential smoothing approac...

In this paper, we study the influence of seasonal demands and forecasts on performance an Automatic Pipeline, Variable Inventory, Order-Based, Production Control System (APVIOBPCS) using linear control theory. particular, consider a system that uses forecast based no-trend, additive-seasonality exponential-smoothing model, compare its to equivalent simple exponential smoothing. We find with for...

the relationship between financial ratios and stock return has been studied in many researches and the presence of income smoothing in tehran stock exchange (tse) has been verified. because of importance of financial reports in predicting and decision making process, income smoothing would be a critical factor in this area. in this paper, the income smoothing impact on relationship between fina...

The entropy evolution behaviour of a partial differential equation (PDE) in conservation form, may be readily discerned from the sign of the local source term of Shannon information density. This can be easily used as a diagnostic tool to predict smoothing and non-smoothing properties, as well as positivity of solutions with conserved mass. The familiar fourth order diffusion equations arising ...

The Double Exponential Smoothing (DES) and Triple (TES) are forecasting methods that require two three smoothing parameters, respectively. parameters often determined through a trial error process is not really efficient since many experiments need to be done. Therefore, in this study, parameter estimation algorithm conducted the form of modified Golden Section Search (GSS) obtain optimal from ...

This paper presents a dynamically optimized fluctuation smoothing rule to improve the performance of scheduling jobs in a wafer fabrication factory. The rule has been modified from the four-factor bi-criteria nonlinear fluctuation smoothing (4f-biNFS) rule, by dynamically adjusting factors. Some properties of the dynamically optimized fluctuation smoothing rule were also discussed theoretically...

In modern textile manufacturing industries, the function of human eyes to detect disturbances in the production processes which yield defective products is switched to cameras. The camera images are analyzed with various methods to detect these disturbances automatically. There are three parts of texture analysis which are going to be studied here, i.e., image smoothing, texture synthesis and d...

3D printing services are appearing, allowing consumers or businesses to order custom parts for delivery within a quoted lead-time, regardless of design specification. The manufacturer’s problem is to ensure that customers receive their goods on time, while capacity costs (including overtime costs) are kept low. We introduce a performance measure called the service rate, analogous to the fill ra...
