This paper focuses on the development of simulation-based environment for multi-echelon cyclic planning and optimisation in the product maturity phase. It is based on integration of analytical and simulation techniques. Analytical techniques are used to obtain initial planning decisions under conditions of stochastic demand and lead time, whereas simulation techniques extend these conditions to...

An environmentally friendly, green, and highly efficient process for the synthesis of biologically and pharmacologically  4H-benzo[b]pyrans  and  3,4-dihydropyrano [c] chromenes  is  developed  by condensing cyclic aromatic aldehydes, malononitrile, and dimedone or 4‐hydroxycoumarin in the presence  of  lactic  acid  as  an  efficient  and  green  catalyst.  The corresponding  products  have  b...

We formulate a nonparametric technique for estimating the mean-value function of a nonhomogeneous Poisson process having a long-term trend or some cyclic effect(s) that may lack familiar trigonometric characteristics such as symmetry over the corresponding cycle(s). This multiresolution procedure begins at the lowest level of resolution by estimating any long-term trend in the target counting p...

The problem of cyclic scheduling of multimodal cyclic processes (MCPs) is considered. The issue follows the production engineering and supply chains environment, where the imposition of the integer domain results (due to inherent process features such as discrete slot sizes, etc.) in the Diophantine character of a scheduling problem. Consequently, some classes of MCPs scheduling problems can be...

We formulate a nonparametric technique for estimating the (cumulative) mean-value function of a nonhomogeneous Poisson process having a long-term trend or some cyclic e€ect(s) that may lack familiar trigonometric characteristics such as symmetry over the corresponding cycle(s). This multiresolution procedure begins at the lowest level of resolution by estimating any long-term trend in the targe...

Bicyclic aziridines show exclusive photochromic behavior. Here, we summarize the results of optical and electrochemical properties, such as photochemical, solvatochromic, electrochromic andkinetic behavior of bicyclic aziridines linked to chalcone moieties. The photochromic process for conversion of closed photoisomers to open photoisomers for compounds 1-10 followed zero-order kinetics. For co...

Cyclic debugging is one of the most important and most commonly used activities in program development. During cyclic debugging, the program is repeatedly reexecuted to track down errors when a failure has been observed. This process necessitates reproducible program executions. Applying classical debugging techniques such using breakpoints or single stepping in real-time systems change the tem...

We demonstrate high-resolution fluorescence microscopy based on a cyclic sequential multiphoton (CSM) process, which gives rise to fluorescence emission following a sequence of cyclic transitions between the bright and dark states of a fluorophore induced by pump and reverse light. By temporally modulating the reverse intensity, we can extract the fluorescence signal generated through the CSM p...

In this paper we describe an elimination process which is a deterministic rewriting procedure that on each elementary step transforms one system of equations over free groups into a finitely many new ones. Infinite branches of this process correspond to cyclic splittings of the coordinate group of the initial system of equations. This allows us to construct algorithmically Grushko’s decompositi...

In this paper, we will address the cyclic scheduling problem with limited WIP (Work-in-process). In these systems, we have to minimize the cycle time of the production while working with a limited level of WIP. We consider here production systems with linear jobs (every operation was followed and preceded by only one operation). Many methods have been proposed to solve the cyclic scheduling pro...
