The production task queue has a great significance for manufacturing resource allocation and scheduling decision. Man-made qualitative queue optimization method has a poor effect and makes the application difficult. A production task queue optimization method is proposed based on multi-attribute evaluation. According to the task attributes, the hierarchical multi-attribute model is established ...

Parts manufactured to tolerances have variations in shape. Most previous work in robotic manipulation assumes that parts do not have shape variations. Orienting devices such as bowl feeders often fail due to variations in part shape. We study the effects of uncertainty in part shape on orienting to develop systems that can orient toleranced polygonal parts. We present a tolerance model in which...

Following the challenges of European Union (EU), member states have adopted circular economy (CE) plans and strategies, with objectives measures to foster circularity. Although concept CE refers various natural resources such as water land, little is known on how current policies are integrating these environmental resources. This article assesses land concerns embedded in EU action issued 2015...

Abstract This paper provides a legal assessment of the EU circular economy action plans [2015, 2020] to determine whether their implementation aims at transformative change or is embedded in prevailing neoliberal ideology. Measures intended promote (CE) are classified according public private nature, degree intervention (command and control, economic instruments, information, self-control). It ...

We consider the problem of existence of entire solutions to the Allen-Cahn equation Δu + u - u(3) = 0 in , usually regarded as a prototype for the modeling of phase transition phenomena. In particular, exploiting the link between the Allen-Cahn equation and minimal surface theory in dimensions N ≥ 9, we find a solution, u, with ∂(x(N))u > 0, such that its level sets are close to a nonplanar, mi...

We study a singular limit problem of the Allen-Cahn equation with Neumann boundary conditions and general initial data of uniformly bounded energy. We prove that the time-parametrized family of limit energy measures is Brakke’s mean curvature flow with a generalized right angle condition on the boundary.

This paper presents a new methodology based on AHP and ANP (Saaty, 1980, 1996) to estimate the value and transfer fees of professional football players. The paper extends the AHP multicriteria methodology proposed by Moreno-Jiménez et al. (2010) for estimating the value of these sportsmen. The new approach multiplicatively combines the (intrinsic) value of the player (estimated by means of AHP ...
