In this paper, an Economic Manufacturing Quantity (EMQ) is set up under the effect of reliability with demand based on the selling price and seasonal time. The profit of the concern is absolutely depending on the manufacturing of the number of products equalizing the seasonal demand created for the product in the particular time and on the other hand based on fixing the selling price matching w...
Why do private firms invest in innovation? Surely the answer to this question is related to the benefits that firms obtain from improving their technology or production processes. In particular, the rate of innovation has been traditionally linked to the capacity of firms to generate profits from these innovations. These profits, in turn, are used by firms to finance their investments in techno...
In this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (EPQ) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. In one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. The c...
A Fibonacci string of length $n$ is a binary string $b = b_1b_2ldots b_n$ in which for every $1 leq i < n$, $b_icdot b_{i+1} = 0$. In other words, a Fibonacci string is a binary string without 11 as a substring. Similarly, a Lucas string is a Fibonacci string $b_1b_2ldots b_n$ that $b_1cdot b_n = 0$. For a natural number $ngeq1$, a Fibonacci cube of dimension $n$ is denoted by $Gamma_n$ and i...
this paper aims at investigating evidentiality in contemporary persian from a typological point of view. first the category of evidentiality and its types in the languages of the world is introduced. gathering and analysing data of spoken and written form of this language as well as classic texts, an attempt was made to see whether evidentiality exists in this language as a grammatical categor...
This paper extends an imperfect production inventory model to machine breakdown at a random time and rework of defective items. Any manufacturing system wants to produce perfect quality items. But in long run production process, there may arise different types of difficulties like labor problem, rawmaterial problems, operator problems, etc., due to that the machinery systems shift from in-contr...
Conditions are given which imply that certain non-autonomous analytic iterated function systems (NIFSs) in the complex plane C have uniformly perfect attractor sets, while other conditions th...
Roussel and Rubio proved a lemma which is essential in the proof of the Strong Perfect Graph Theorem. We give a new short proof of the main case of this lemma. In this note, we also give a short proof of Hayward’s decomposition theorem for weakly chordal graphs, relying on a Roussel–Rubio-type lemma. We recall how Roussel–Rubio-type lemmas yield very short proofs of the existence of even pairs ...
The Euler equations for a non-homogeneous, non-viscous ~ompressible fluid are shown to be well-posed for a short time interval~ using techniques of infinite dimensional geometry and a weighted Hodge theorem. Regularity and other properties of these solutions are pointed out as well. !. Introduction. In [2], D. Ebin and the author introduced a technique for solving the Euler equations for a perf...
