“…The significant competitive parameter is a high due date adherence, in other to prevent instability in the mix end products to be produced which can cause the customization which significantly shares of the distributed end products that are exceptional and to prevent creating variable load for departments preparing new items for manufacturing and assembly for the construction department [22]. As the demand for customization fluctuate Periodic capacity deficits are likely to arise in preproduction departments, causing the release of work orders to slow down from the overdue start of manufacturing which makes it a necessity to updated or generated routines and operation times, The Bill of Materials (BOM) and NC-programs [23].…”

Production is one of the most important activities which guarantee the continued existence of man; however, it comes with its challenges which make it very difficult to meet up the consumer’s demand. In this regard, the system is required by production and manufacturing companies, human resources, and materials to be enhanced by scheduling and planning of production. In addressing this problem of scheduling over a mid-term possibility, material flow and production objectives should be forecast by solving the problems of planning. Only when the production planning problems have been solved then scheduling problems could be addressed. In this work, we relate scheduling with capacity planning in relation to the production of goods and services. Also reviewed the common problems associated with the industry and how they are overcome.

“…Electromechanical constants of composites' constituents. [13,15] PZT Once the solutions of fiber coefficients are obtained, the corresponding matrix unknowns can be derived through Equation ( 31) and (32), finally giving full access to the local elastic and electric field within square or hexagonal unit cells. The effective piezoelectric coefficients can thus be predicted through integrating over the unit cell's domain that is elaborated in the next section.…”

“…[ 32 ] Still, based on the mesh discretization of RUCs, FVDAM adopts surface‐averaged continuities among adjacent subvolumes instead of node‐to‐node continuities by finite element methods (FEM) and is thus treated as an attractive alternative to the most dominant FEM. [ 33 ] Recently Chen et al, [ 13,34 ] expanded the FVDAM with Multiphysics capability and several results are employed herein for comparison.…”

“…In addition, the finite volume (FV) concept that was originally developed for fluid mechanics was introduced into the micromechanics to study the multiphysics effect of piezoelectric composites. [14,15] The two-scale homogenization framework was also proposed for elastoÀelectric composites based on the so-called FE 2 technique. [16,17] The advantages of numerical methods can be attributed to their flexibility in the investigation of complex geometric effect [18] and localized stress recovery.…”

Herein, the elasticity‐based locally exact homogenization theory (LEHT) is extended to study the effective and localized responses of piezoelectric fiber composites. Based on the Trefftz concept, coupled internal solutions for electric fields and elastic displacements are developed for repeating unit cells (RUCs) that are characterized from the composite domain. The unknown coefficients of the internal fields can be determined by imposing interfacial continuity conditions between fiber and matrix and implementing the newly proposed multiphysics periodic boundary conditions. Finally, the generalized constitutive relations are established to predict the effective coefficients. The accuracy of the proposed technique is tested by validating the present simulations against the analytical Eshelby solution and asymptotic method, classical Mori−Tanaka (M−T) model, finite element (FE)‐ and finite volume (FV)‐based methods, as well as the experimental measurement in the literature with excellent agreement. What is more, several microstructural effects, such as phase volume fraction, fiber arrangement, etc., are varied to test their effects on the piezoelectric composites at both homogenized and localized levels. Based on the presented computational efficiency, the multiphysics LEHT is encapsulated into a blackbox with input/output data constructions for easy implementation by professionals or nonprofessionals.
