In this paper we develop a polynomial-time approximation scheme for a particular
case of the two-machine flow shop scheduling problem with several availability
constraints on the second machine under the resumable scenario.

Most practical textile models are based on a two scale approach: a
one-dimensional fiber model and a fabric model, see Fan et al. (Commun Comput
Phys 4(4):929–948, 2008). No meso-level is used in between, i.e. the yarn scale
is neglected in this setup. For dense textile substrates this seems appropriate
as the yarns connect everywhere, but for loose fabrics or scrims this approach
cannot be kept. ... hiện toàn bộ
In this paper, a pair of Mond-Weir type higher order fractional symmetric dual
program over cone constraints is formulated. Under higher order invexity
assumptions, we prove weak, strong and strict duality theorems. Moreover, a self
dual program is formulated and self duality theorem is discussed.
